and the corpse of Jezebel shall be as dung on the face of the field in the territory of Jezreel, so that no one can say, This is Jezebel.’”
The greatest delinquent in the house of Ahab was Jezebel: it was she that introduced Baal, slew the Lord's prophets, contrived the murder of Naboth, stirred up her husband first, and then her sons, to do wickedly; a cursed woman she is here called (Kg2 9:34), a curse to the country, and whom all that wished well to their country had a curse for.
Commenting on 2 Kings 9:30-37
And the carcase of Jezebel shall be as dung upon the face of the field in the portion of Jezreel; [so] that they shall not say, This [is] Jezebel. (p) Thus God's judgments appear even in this world against those who suppress his word and persecute his servants.
And the carcass of Jezebel shall be as dung - As it was not buried under the earth, but was eaten by the dogs, this saying was also literally fulfilled. They shall not say, This is Jezebel - As she could not be buried, she could have no funeral monument. Though so great a woman by her birth, connections, and alliances, she had not the honor of a tomb!
