My people ask counsel at their stocks,.... Or "at his wood", or stick; his wooden image, as the Targum; their wooden gods, their idols made of wood, mere stocks and blocks, without life or sense, and much less reason and understanding, and still less divinity. Reference is here had either to the matter of which an idol was made, being the trunk of a tree, or a block of wood; as the poet introduces Priapus saying, "olim truncus eram ficulnus, inutile lignum": or to sticks of wood themselves, without being put into any form or shape; for so it is reported, that the ancient idolaters used to receive for gods, with great veneration, trees or pieces of wood, having the bark taken off; particularly the Carians worshipped for Diana a piece of wood, not hewed, squared, דענאלפ רס: though the first seems rather to be the sense here; and either was extremely foolish. And yet such was the stupidity of this people, whom God had formerly chose for his people and had distinguished them by his favours from others, and they had professed themselves to be his people, and as yet were not utterly cast off, as to forsake him and his divine oracles, and all methods of knowing his will; as to ask counsel of such wooden deities in matters of moment and difficulty, what should be done by them, or concerning things to come.
And their staff declareth unto them; what methods are to be taken by them in the present case, or what shall come to pass, as they fancy; that is, either their idol, made of a staff or stick of wood, or a little image carried on a staff; such as probably were the teraphim they consulted, instead of the Urim and Thummim; and imagined they declared to them what they should do, or what would befall them. Kimchi's father interprets it of the false prophets on whom they depended, and whose declarations they received as oracles. Perhaps some respect is had to a sort of divination used among the Heathens by rods and staves, called "rhabdomancy", which the Jews had learnt of them; like that by arrows used by Nebuchadnezzar, Eze 21:21. This was performed by setting up a stick or staff, and as that fell, so they judged and determined what was to be done. The manner, according to Theophylact on the place, was this,
"they set up two rods, and muttered some verses and enchantments; and then the rods falling through the influence of demons, they considered how they fell, whether forward or backward, to the right or the left; and so gave answers to the foolish people, using the fall of the rods for signs.'' The Jews take this to be forbid by that negative precept, De 18:10, "there shall not be found among you any that useth divination". So Jarchi and Baal Hatturim on that text explain a diviner by one that holds his staff; and the former adds and says, shall I go, or shall I not go? as it is said, "my people ask counsel at their stocks", &c.; the manner of which they thus describe,
"when they are about to go on a journey, they inquire before they set out, i.e. whether it will be prosperous or not; and the diviner takes a branch of a tree, and takes off the bark on one side, and leaves it on the other, and then throws it out of his hand; if, when it falls, the bark is uppermost, he says, this is a man; then he casts it again, and if the white is uppermost, this is a woman; to a man, and after that a woman, this is a good sign, and he goes his journey, or does what be desires to do: but if the white appears first, and after that the bark, then he says, to a woman, and after that a man, and he forbears (that is, to go on his journey, or do what he desired): but if the bark is uppermost in both (throws), or the white uppermost in both, to a man after a man, and a woman after a woman, then his journey (as to the success of it) is between both; and so they say they do in the land of Slavonia.'' And from the Slavonians, Grotius says, the Germans took this way of divination, of which Tacitus gives an account; and it seems by him that the Chaldeans also had it, from whom the Jews might have it. This way of divination by the staff is a little differently given in Hascuni: the diviner measures his staff with his finger, or with his hand; one time he says, I will go; another time, I will not go; but if it happens, at the end of the staff, I will not go, he goes not.
For the spirit of whoredom hath caused them to err; a violent inclination and bias of mind to idolatry, which is spiritual adultery, and a strong affection for it, stirred up by an evil spirit, the devil; which so wrought upon them, and influenced them, as to cause them to wander from the true God, and his worship, as follows:
and they have gone a whoring from under their God; or
"erred from the worship of their God,'' as the Targum; from the true God, who stood in the relation of a husband to them; but, led by a spirit of error, they departed from him, and committed spiritual adultery, that is, idolatry; which is explained and enlarged upon in the next verse.
