The Prophet calls here the Israelites the people of God, not to honor them, but rather to increase their sin; for the more heinous was the perfidy of the people, that having been chosen, they had afterwards forsaken their heavenly Father. Hence My people: there is here an implied comparison between all other nations and the seed of Abraham, whom God had adopted; "This is, forsooth! the people whom I designed to be sacred to myself, whom of all nations in the world I have taken to myself: they are my heritage. Now this people, who ought to be mine, consult their own wood, and their staff answers them!" We hence see that it was a grievous and severe reprobation when the Lord reminded them of the invaluable kindness with which he had favored the children of Abraham. So at this day our guilt will be more grievous, if we continue not in the pure worship of God, since God has called us to himself and designed us to be his peculiar flock. The same thing that the Prophet brought against the Israelites may be also brought against the Papists; for as soon as infants are born among them, the Lord signs them with the sacred symbol of baptism; they are therefore in some sense (aliqua ex parte) the people of God. We see, at the same time, how gross and abominable are the superstitions which prevail among them: there are none more stupid than they are. Even the Turks and the Saracenes are wise when compared with them. How great, then, and how shameful is this baseness, that the Papists, who boast themselves to be the people of God, should go astray after their own mad follies! But the Prophet says the Israelites "consulted" their own wood, or inquired of wood. He no doubt accuses them here of having transferred the glory of the only true God to their own idols, or fictitious gods. They consult, he says, their own wood, and the staff answers them. He seems, in the second clauses to allude to the blind: as when a blind man asks his staff, so he says the Israelites asked counsel of their wood and staff. Some think that superstitions then practiced are here pointed out. The augurs we know used a staff; and it is probable that diviners in the East employed also a staff, or some such thing, in performing their incantations. [1] Others explain these words allegorically, as though wood was false religion, and staff the ungodly prophets. But I am inclined to hold to simplicity. It then seems to me more probable, that the Israelites, as I have already stated, are here condemned for consulting wood or dead idols, instead of the only true God; and that it was the same thing as if a blind man was to ask counsel of his staff, though the staff be without any reason or sense. A staff is indeed useful, but for a different purpose. And thus the Prophet not only contemptuously, but also ironically, exposes to scorn the folly of those who consult their gods of wood and stone; for to do so will no more avail them than if one had a staff for his counselor. He then subjoins, for the spirit of fornication has deceived them Here again the Prophet aggravates their guilt, inasmuch as no common blame was to be ascribed to the Israelites; for they were, he says, wholly given to fornication The spirit, then, of fornication deceived them: it was the same as if one inflamed with lust ran headlong into evil; as we see to be the case with brutal men when carried away by a blind and shameful passion; for then every distinction between right and wrong disappears from their eyes -- no choice is made, no shame is felt. As then such heat of lust is wont sometimes to seize men, that they distinguish nothing, so the Prophet says with the view of shaming the people the more, that they were like those given to fornication, who no longer exercise any judgment, who are restrained by no shame. The spirit, then, of fornication has deceived them: but as this similitude often meets us, I shall not dwell upon it. They have played the wanton, he says, that they may not obey the Lord. He does not say simply, from their God,' but from under' mtcht, metachet, They have then played the wanton, that they might no more obey God, or continue under his government. We may hence learn what is our spiritual chastity, even when God rules us by his word, when we go not here and there and rashly follow our own superstitions. When we abide then under the government of our God, and with fixed eyes look on him, then we chastely preserve our faithfulness to him. But when we follow idols, we then play the wanton and depart from God. Let us now proceed --

Footnotes

1 - This was probably similar to divination by arrows, mentioned in Ezekiel 21:21. There is a practice of this kind still among the Arabs, as Adam Clarke mentions in his comment on this verse. They take three arrows without head, and write onone, Command me, Lord; on the other, Forbid me, Lord; and the third is left a blank. These are put in a bag, and one is drawn. If the first is drawn, they do what they intend; if the second, they abstain for a year; if the third, they draw again. -- Ed.

My people ask counsel at - (literally, "on") their stocks They ask habitually ; and that, in dependence "on their stocks." The word "wood" is used of the idol made of it, to bring before them the senselessness of their doings, in that they asked counsel of the senseless wood. Thus Jeremiah reproaches them for "saying to a stock, my father" Jeremiah 2:27; and Habakkuk, "Woe unto him that saith to the wood, awake" Habakkuk 2:19.
And their staff declareth unto them - Many sorts of this superstition existed among the Arabs and Chaldees. They were different ways of drawing lots, without any dependence upon the true God to direct it. This was a part of their senselessness, of which the prophet had just said, that their sins took away their hearts. The tenderness of the word, "My people," aggravates both the stupidity and the ingratitude of Israel. They whom the Living God owned as His own people, they who might have asked of Him, asked of a stock or a staff.
For the spirit of whoredoms - It has been thought of old, that the evil spirits assault mankind in a sort of order and method, different spirits bending all their energies to tempt him to different sins . And this has been founded on the words of Holy Scripture, "a lying spirit," "an unclean spirit," "a spirit of jealousy," and our Lord said of the evil spirit whom the disciples could not cast out; "This kind goeth not out but by prayer and fasting" Matthew 17:21. Hence, it has been thought that "some spirits take delight in uncleanness and defilement of sins; others urge on to blasphemies; others, to anger and fury; others take delight in gloom; others are soothed with vainglory and pride; and that each instills into man's heart that vice in which he takes pleasure himself; yet that all do not urge their own perversenesses at once, but in turn, as opportunity of time or place, or man's own susceptibility, invites them" . Or the word, "spirit of whoredoms," may mean the vehemence with which people were whirled along by their evil passions, whether by their passionate love of idolatry, or by the fleshly sin which was so often bound up with their idolatry.
They have gone a whoring from under their God - The words "from under" continue the image of the adulteress wife, by which God had pictured the faithlessness of His people. The wife was spoken of as "under her husband Numbers 5:19, Numbers 5:29; Ezekiel 23:5, i. e., under his authority; she withdrew herself "from under" him, when she withdrew herself from his authority, and gave herself to another. So Israel, being wedded to God, estranged herself from Him, withdrew herself from His obedience, cast off all reverence to Him, and prostituted herself to her idols.

At their stocks - They consult their wooden gods.
And their staff declareth - They use divination by rods; see the note on Ezekiel 21 (note), where this sort of divination (rabdomancy) is explained.

My (n) people ask counsel at their stocks, and their staff declareth unto them: for the (o) spirit of whoredoms hath caused [them] to err, and they have gone a whoring from under their God.
(n) Thus he speaks by derision in calling them his people, who now because of their sins they were not his people: for they sought help from stocks or wooden images and sticks or idols.
(o) They are carried away with madness.

My people ask counsel at their stocks,.... Or "at his wood" (a), 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 (b) 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 (c), 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, or planed (d): 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, Ezekiel 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, Deuteronomy 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 (e),
"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 (f) 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: (g) 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.

The people consulted images, and not the Divine word. This would lead to disorder and sin. Thus men prepare scourges for themselves, and vice is spread through a people. Let not Judah come near the idolatrous worship of Israel. For Israel was devoted to idols, and must now be let alone. When sinners cast off the easy yoke of Christ, they go on in sin till the Lord saith, Let them alone. Then they receive no more warnings, feel no more convictions: Satan takes full possession of them, and they ripen for destruction. It is a sad and sore judgment for any man to be let alone in sin. Those who are not disturbed in their sin, will be destroyed for their sin. May we be kept from this awful state; for the wrath of God, like a strong tempest, will soon hurry impenitent sinners into ruin.

Instances of their understanding ("heart") being "taken away."
stocks--wooden idols (Jeremiah 2:27; Habakkuk 2:19).
staff--alluding to divination by rods (see on Ezekiel 21:21-22). The diviner, says ROSENMULLER, threw a rod from him, which was stripped of its bark on one side, not on the other: if the bare side turned uppermost, it was a good omen; if the side with the bark, it was a bad omen. The Arabs used two rods, the one marked God bids, the other, God forbids; whichever came out first, in drawing them out of a case, gave the omen for, or against, an undertaking.
declareth--that is, is consulted to inform them of future events.
spirit of whoredoms--a general disposition on the part of all towards idolatry (Hosea 5:4).
err--go astray from the true God.
from under their God--They have gone away from God under whom they were, as a wife is under the dominion of her husband.

Stocks - Wooden statues. The spirit of whoredom - A heart ensnared with whoredoms, spiritual and corporal. Caused them to err - Hath blinded, and deceived them.
