Midrash su I Re 16:31

And Israel beheld Joseph’s sons, and said: “Who are these?” (ibid., v. 8). R. Judah the son of Shalum asked: Is it possible that he did not recognize them? Had they not sat and studied the law with him every day? Yet now he asked “Who are these?” even though they had ministered to him during the seventeen years he had resided in Egypt. Did he actually not recognize them? The fact is that he foresaw that Jeroboam the son of Nebat and Ahab the son of Omri would descend from Ephraim, and that they would become idolaters.¹⁰Jeroboam made two calves of gold, placing one in Beth-El, and the other in Dan (I Kings 12:28). Ahab married the Phoenician princess Jezebel, who introduced the worship of Baal and Astarte into the northern kingdom. And he went and served Baal and worshipped him (I Kings 16:31). It was for this reason the Holy Spirit departed from him. When Joseph realized this, he prostrated himself before the Holy One, blessed be He, and pleaded for mercy, saying: “Master of the Universe, if they are worthy to be blessed, do not turn away and cause me to be turned away today disgraced.” Thereupon the Holy One, blessed be He, restored the Holy Spirit to Jacob, and he blessed them. Whence do we know this? From the fact that it is written: And I, I taught Ephraim to walk, taking them by their arms (Hos. 11:3), that is, I restored the Holy Spirit to Jacob for the sake of Ephraim.

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).
