Abel Mitsrayim means "meadow of Egypt" or "mourning of Egypt." It is a place at the threshing floor of Atad, east of the Jordan, where the Egyptians and Israelites mourned deeply for the patriarch Jacob.
The double meaning of abel — meadow and mourning — creates a wordplay in Genesis 50. The Canaanites witnessed the great mourning of Egypt and named the place accordingly: the mourning of Egypt. Jacob's death becomes a public testimony, drawing even Egypt's attention to the God-honoring grief of His people. It also points toward the Exodus — a nation that once mourned for Israel's patriarch would one day mourn as Israel departed.
