Genesis 50:7-11

7So Joseph left to bury his father. All Pharaoh’s officials, the leaders in his palace staff, and all the leaders of Egypt went with him.

8Joseph’s household, his brothers, and his father’s household also went with him. (Only their children, their flocks, and their cattle were left in Goshen.)

9Chariots and horsemen went with him. It was a very large group.

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].
