The leaders of this people cause them to err (comp. Isaiah 3:12). Both the peoples were led into idolatry by their rulers, but Israel especially. Jeroboam, the first king, introduced the calf-worship, and his successors from first to last persisted in his sin.
Ahab added the still grosset idolatry of Baal. Those who held high position under the kings were equally bad examples to the people (see above, Isaiah 1:2:3). Are destroyed. First, morally corrupted and debased, then physically given over to destruction—slaughtered by Philistines, Syrians, and Assyrians.
