Deuteronomy 18

The church of Jesus Christ is a priesthood (1 Peter 2:5, 9), but the nation of Israel had a priesthood. All the priests and Levites were descendants of Levi, Jacob’s third son by Leah. Levi had three sons—Gershon, Kohath, and Merari—and Aaron and Moses were from the family of Kohath (Ex. 6:16–25). Only the descendants of Aaron were called “priests” and were allowed to serve at the altar and in the sanctuary proper. The Levites, who were descendants of Gershon and Merari, assisted the priests in the many ministries connected with the altar and the sanctuary. Neither the priests nor the Levites were given any inheritance in the land of Israel (Deut. 10:8–9; 12:12, 18–19) but lived from the tithes, offerings, and sacrifices that were brought to the sanctuary.

The priests (vv. 3–5). The priests were to receive specified parts from the sacrifices, except for the burnt offering, which was totally consumed on the altar. They would burn a handful of the meal offering on the altar and keep the rest for themselves, and various parts of the animal sacrifices were given to them as their due (Lev. 6:8—7:38). They were also given the firstfruits of the grain, oil, wine, and wool. This Old Testament practice carries over into the New Testament ministry. “Do you not know that those who minister the holy things eat of the things of the temple, and those who serve at the altar partake of the offerings of the altar? Even so the Lord has commanded that those who preach the gospel should live from the gospel” (1 Cor. 9:13–14 nkjv). The Lord’s command is found in Luke 10: and is quoted in 1 Timothy 5:18.

If the people didn’t support the priests as God commanded, then the priests would have to find their support elsewhere, and this would take them away from the ministry at the sanctuary. But only the priests could offer the sacrifices, care for the lamps and the table of bread, and burn the incense on the golden altar. Without the presence of the priests, the ministry at the sanctuary would come to a halt and the people would be without intercession and spiritual help.

The Levites (vv. 6–8). The Levites lived in fortyeight cities scattered throughout the nation of Israel (Josh. 21). We assume that there was a definite schedule that governed their participation at the sanctuary, such as there was in the days of David (1 Chron. 23— 26), with each Levite assigned to a task and a time. The priests and Levites could purchase land if they wanted to (1 Kings 2:26; Jer. 32:7; Acts 4:36–37) and even get an income from the land, but their major interest had to be serving at the sanctuary and helping the people know God and obey His Word. If a Levite sold or leased his property and came to the sanctuary because of his love for the Lord and His house, he must be permitted to serve there and to share in the gifts that the people brought. The fact that he earned money by leasing or selling his land did not change this policy.

In the time of Nehemiah, the people didn’t faithfully bring their tithes and offerings to the temple, and some of the Levites had to return to their lands in order to live (Neh. 13:10–14). Nehemiah urged the people to obey the Word and support their spiritual leaders, and they brought their tithes and offerings to be distributed to the Levites. It’s tragic the way professed Christians fail to support their churches by faithfully bringing their tithes and offerings, yet expect their churches to help them when they have needs.

If people don’t know the true and living God and don’t have His Word to guide them, they have to find substitutes to help them make decisions and face up to the demands of life. Instead of worshipping the true and living God, the people in Canaan worshipped dead idols (Ps. 115), and for the Word of God they substituted superstitious practices that linked them to Satan and his demonic forces. No matter what the experts in “comparative religions” might say, pagan idolatrous religion is Satan worship (1 Cor. 10:14–22; Rev. 9:20). The explosion of the occult that we’ve seen in recent years is evidence that people are seeking in the wrong direction for the spiritual help they need. Visit any large secular bookstore and you’ll find shelves of books devoted to Satan, demons, black magic, and allied themes. People who refuse to love the truth must end up believing lies (2 Thess. 2:7–12), and only Jesus Christ can deliver them from the bondage that these occult practices bring to their lives.

The abominations of Satan (vv. 9–13). God forbids His people to have anything to do with occult practices. Moses had already mentioned some of these “abominations” (vv. 9, 12; “detestable practices,” niv) and warned Israel not to meddle with them (Ex. 22:18; Lev. 17:7; 19:26, 31; 20:6, 27), so this wasn’t an entirely new theme, but here he went into greater detail. The false prophet Balaam discovered that no sorcery could work against Israel (Num. 23:23), but the Jews could ensnare themselves if they investigated these dangerous practices and got themselves involved. One reason God commanded Israel to wipe out the nations in Canaan was because of their evil occult practices (18:14), and why should the conqueror follow the religion that brought judgment to the conquered?

Lest we conclude that these warnings about the occult don’t apply to Christians in this “enlightened age,” we need to be reminded that idolatry and witchcraft are listed among the sins of the flesh in Galatians 5:19–21, and that the book of Revelation teaches that occult practices will be very widespread in the end times (9:20–21; 18:2). In fact, those who engage in such things are among the ones destined for the lake of fire (21:8; 22:14–15).

In Deuteronomy 18:10–11, Moses listed the practices that were forbidden by God, beginning with sacrificing children, a subject we’ve already discussed (12:31). If you want to worship Satan, you have to pay the price he demands. He will give you what you want if you give him what he wants. He offered Jesus the kingdoms of the world in return for one act of worship (Matt. 4:8–10), and he sneered at Job and claimed that he worshipped God only because the Lord rewarded him (Job 1—2). There are poems, novels, and plays in ancient and modern literature telling about people who sold themselves to Satan, received their rewards, and then regretted they had ever entered into the bargain. Perhaps the most famous is Goethe’s Tragedy of Dr. Faustus.

The second forbidden practice is divination, which is seeking to get secret knowledge, especially about future events. Divination was widely practiced in the ancient world in various ways, including interpreting omens, consulting the stars, inspecting various animal organs, using divining rods, interpreting dreams, watching the movement of the water, and contacting the dead (1 Sam. 28). In some way, the sacrificing of children was also involved in divination. Mediums, necromancers, and spiritists consulted the dead with the hopes of learning forbidden things about the future.

The diviner wants to know the future, but the sorcerer wants to control people and the future by using various forms of magic, witchcraft, and spells. By being in league with the demons and casting spells, magicians and witches seek to influence people and events to achieve their own selfish purposes. People in today’s “scientific world” may scoff at these things, but any evangelical missionary can tell you of the demonic influence that has held many backward peoples in bondage and fear. Certainly demonic forces are at work in the “modern” Western world today, but they operate with greater subtlety and aren’t always easily detected. Those who would deny the influence of demons in the church today will have to explain the prevalence of demonism when Christ was here on earth and His victory over demons. They must also consider our Lord’s commission to His disciples (Mark 3:14–25; Luke 9:1) and their experience ministering to the demonized (10:17). And what about the ministry of Paul (Acts 19:11) and what Paul wrote about demons to believers in the churches (1 Cor. 10:20–21; Rom. 8:37–39; Eph. 6:10–18)?

If any Jew ever considered getting personally acquainted with these wicked practices, he would have to consider Moses’ closing admonition, “You must be blameless before the Lord your God” (Deut. 18: niv). “Blameless” implies, not sinless perfection, but a heart totally devoted to the Lord. It speaks of integrity and an undivided heart, what David meant when he wrote, “I will walk within my house with a perfect heart” (Ps. 101: nkjv). The Jewish “Shema” declared, “Love the Lord your God with all your heart and with all your soul and with all your strength” (Deut. 6: niv).

The revelation of the true God (vv. 14–19). Israel didn’t need to experiment with new religions because the Lord had revealed Himself and His Word to them through Moses His chosen prophet. Once you have the real thing, why go in search of substitutes? Israel could have said to the nations in Canaan what Jesus said to the Samaritan woman at Jacob’s well, “You worship what you do not know; we know what we worship, for salvation is of the Jews” (John 4: nkjv). In this statement, Jesus rejected all other religions except Old Testament Judaism and New Testament Christianity, and Christianity came out of Judaism and fulfilled it.

Moses promised the people that God would raise up other prophets as the nation needed them, and the people were to give heed to their message and obey it, for their message would be the Word of God. Moses reminded the people that at Sinai they had requested that he give them God’s message, because they were afraid to hear God’s voice (Ex. 20:18–21). Not all the prophets wrote down their messages for future generations to read and study, but Moses did and so did Isaiah, Jeremiah, Ezekiel, Daniel, and the twelve men we call “the minor prophets.” These prophets not only rebuked Israel for sin and encouraged them in holy living, but they pointed to the coming of the Messiah who would be the Savior of the world. During His walk with the two Emmaus disciples, Jesus began at “Moses and all the prophets” and “expounded to them in all the Scriptures the things concerning Himself” (Luke 24: nkjv).

Over the centuries, Jewish scholars interpreted Deuteronomy 18: to refer to a special prophet who would appear before Messiah came to establish His kingdom. From Malachi 4:5, the Jews knew that Elijah would return at the end of the age, and they wondered if it was John the Baptist, who dressed and ministered so much like Elijah (Luke 3:1–9; Matt. 3:4). John denied it and also denied that he was the prophet that Moses promised (John 1:19–21). In one sense, John was an “Elijah” who prepared the way for Christ (Matt. 11:14; 17:12; Luke 1:13–17), but John did not identify himself as the fulfillment of Malachi 4:5. (On Moses’ writing about the Christ, see John 1:19–28, 45; 5:46; 6:14; 7:40.)

Moses was doing more than promise the whole line of prophets that the Lord would send; he was also announcing the coming of the Prophet, the Lord Jesus Christ. At least that’s the way Peter explained it in Acts 3:22–26. Our Lord has three offices, that of Prophet, Priest, and King. When He ministered here on earth, He declared God’s Word as Prophet, and by the inspiration of His Spirit has caused it to be written down for our learning. He intercedes for His people as the High Priest in heaven, and He also sits on the throne and reigns as King, working out His purposes in this world (1 Cor. 15:25; Eph. 1:18–23). One day He will return and reign on earth as King of kings (Rev. 19:11ff.).

It’s a serious thing to hear God’s Word and not respect it and obey it, for it is the Word of the living God, the God of truth. The written Scriptures are a priceless treasure; they teach us what we need to know about God, the way of salvation, and how to live godly lives and please Him. There is no substitute for the Word of God. Peter was right: “Lord, to whom shall we go? You have the words of eternal life” (John 6:68).

The identification of true prophets (vv. 20–22). Moses promised that there would be prophets sent by God to Israel to teach them what they needed to know, but the logical question people would ask was, “How can we distinguish a true prophet from a false prophet?” Moses had already told them that everything a prophet says and does must be tested by the Word of God (13:1–5), and he repeated that warning. “But the prophet who presumes to speak a word in My name, which I have not commanded him to speak, or who speaks in the name of other gods, that prophet shall die” (18: nkjv). This test was valid even if the prophet’s prediction came true or if he performed signs and wonders. But the ultimate test is that God’s true prophets are always 100 percent accurate (v. 22). Modern day “prophets” boast of being 75 percent accurate, or maybe 80 percent, but that admission only brands them as false prophets. A prophet sent by God is never wrong; what he predicts will come to pass.

Believers today must exercise spiritual discernment because “many false prophets are gone out into the world” (1 John 4:1–6). John makes it clear that the first test of a true minister of the Word is the confession that Jesus Christ came in the flesh and is indeed the Son of God. When you listen to a teacher who is truly God’s servant, the Spirit dwelling in your heart will respond to the Word being taught (1 John 2:18–27). The message will be true to the Scriptures and will exalt Jesus Christ.

Moses has been focusing on the true worship of the Lord, a subject that’s very important to the church today. I have traveled enough in this world to know that you meet different styles of worship in different countries and among different peoples. My wife and I have attended formal worship services in cathedrals as well as informal meetings in homes and even out-ofdoors, and our hearts have been blessed. The important thing is not the culture or the setting but that we worship the Lord “in spirit and in truth” (John 4:24). True worship comes from within, from a heart totally yielded to the Lord, and true worship is controlled by the Holy Spirit and the Word of God (Eph. 5:18–21; Col. 3:16–20). Our subjective feelings must be monitored by Scripture and motivated by the Spirit, otherwise we may be engaging in false worship. False worship is dangerous because it may open the door to demonic influences. Satan is a counterfeiter (2 Cor. 11:13–15) who knows how to lead undiscerning people away from Christ and the truth. They think they’re filled with the Spirit when they’re really fooled by the spirits.

“Little children, keep yourselves from idols” (1 John 5:21).
