Midrash sur Rois 2 9:35

Whence do we learn (the duty of) showing loving-kindness to mourners? From Jezebel, the daughter of Ethbaal. The palace of Jezebel, daughter of Ethbaal, was near the market-place. When any corpse was carried through the market-place, she would go forth from her palace, and she clapped with the palms of her hands and praised with her mouth, and she followed the corpse ten steps. Concerning her, Elijah, be he remembered for good, prophesied (and said): "In the portion of Jezreel shall the dogs eat the flesh of Jezebel" (2 Kings 9:36). But over the limbs which were (employed in) showing loving-kindness, the dogs had no power, as it is said, "And they went || to bury her: but they found no more of her than the skull, and the feet, and the palms of her hands" (2 Kings 9:35).
