Genesis 50:10-11

10When they came to the threshing floor  of Atad, which is on the east side of the Jordan River, they began a great and solemn ceremony to mourn Jacob’s death. Joseph took seven days to mourn his father’s death.

11When the Canaanites living there saw the funeral ceremonies at the threshing floor of Atad, they said, “These funeral ceremonies are taken very seriously by the Egyptians.” That’s why that place on the east side of the Jordan was named Abel Mizraim [Egyptian Funeral Ceremonies].
