Esau the Gilded Caldron and the Evil Heart of Haman

Another interpretation of (Genesis 27:1): "And he said to him, 'My son'; and he said to him, 'Here I am.'" And Solomon declared (Proverbs 26:23): "Silver dross overlaid upon earthenware are burning lips and an evil heart." To what was Esau like? To a caldron whose outside is of gold, with pearls set into it, but inside it is of earthenware. So too Esau would say to his father, "Here I am," but in his heart he was saying, "When will he die?" As it is stated (Genesis 27:41): "And Esau said in his heart, 'Let the days of mourning for my father draw near, and I will kill Jacob my brother.'" Behold, "Silver dross overlaid upon earthenware," and so forth. And you find that the seed of Esau, Haman, says in his heart, as it is written (Esther 6:6): "And Haman said in his heart." (Psalms 14:1): "The fool has said in his heart, 'There is no God.'" And you said in your heart (Isaiah 14:13): "I will ascend to the heavens," and so forth. (Ezekiel 38:10): "And it shall come to pass on that day that thoughts shall arise upon your heart," and so forth. (Psalms 10:11): "He has said in his heart, 'God has forgotten.'" (Isaiah 47:8): "And now hear this, O luxurious one who dwells securely, who says in her heart, 'I am, and there is none besides me.'" Behold (Proverbs 26:25), "for there are seven abominations in his heart"; and Solomon declared (Proverbs 26:23), "Silver dross overlaid upon earthenware are burning lips and an evil heart."
