Albert Barnes Commentary 1 Kings 21:11

"And the men of his city, even the elders and the nobles who dwelt in his city, did as Jezebel had sent unto them, according as it was written in the letters which she had sent unto them." — 1 Kings 21:11 (ASV)

The willing submission of the elders and nobles implies a deep moral degradation among the Israelites, which was the fruit of their lapse into idolatry.
