4:12-19 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.
12. Instances of their understanding ("heart") being "taken away."
stocks—wooden idols (Jer 2:27; Hab 2:19).
staff—alluding to divination by rods (see on Eze 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 (Ho 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.
