Genesis 50:10; Genesis 50:11

10 When they reached the threshing floor of Atad, near the Jordan, they lamented loudly and bitterly; and there Joseph observed a seven-day period of mourning for his father.

11 When the Canaanites who lived there saw the mourning at the threshing floor of Atad, they said, “The Egyptians are holding a solemn ceremony of mourning.” That is why that place near the Jordan is called Abel Mizraim.
