Albert Barnes Commentary 1 Kings 21:23

And of Jezebel also spoke the Lord, saying - These are not the words of Elijah, but of the writer, who notes a special prophecy against Jezebel, whose guilt was at least equal to her husband’s.

Wall - The marginal rendering “ditch” is preferable. There is always a space outside the walls of eastern towns that lies uncultivated and is naturally used for the deposit of refuse of every kind. Here the dogs prowl, and the kites and vultures find many a feast.
