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, Eze 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 (Hos 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.
