Adam and Edom (Esau) are basically the same name in Hebrew.
Adam lost his birthright — immortality, and the right to live in Eden — because he ate a piece of fruit.
Edom lost his birthright because he ate a mess of pottage.
Adam was cheated out of his inheritance by the serpent, to whom God said, “Thou shalt bruise his heel” (Genesis 3:15).
Edom was cheated out of his inheritance by Jacob, who “took his brother by the heel in the womb” (Hosea 12:3).
