What does 2 Kings 9:30-37 mean?

When Jehu came to Jezreel, Jezebel heard of it. And she painted her eyes and adorned her head and looked out of the window. And as Jehu entered the gate, she said, “Is it peace, you Zimri, murderer of your master?” And he lifted up his face to the window and said, “Who is on my side? Who?” Two or three eunuchs looked out at him. He said, “Throw her down.” So they threw her down. And some of her blood spattered on the wall and on the horses, and they trampled on her. Then he went in and ate and drank. And he said, “See now to this cursed woman and bury her, for she is a king’s daughter.” But when they went to bury her, they found no more of her than the skull and the feet and the palms of her hands. When they came back and told him, he said, “This is the word of the LORD, which he spoke by his servant Elijah the Tishbite: ‘In the territory of Jezreel the dogs shall eat the flesh of Jezebel, 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.’”
