Gen 50:10-11

10When they came to the threshing floor of Atad, which is beyond the Jordan, they held there a very great and sorrowful lamentation; and he observed a time of mourning for his father seven days.11When the Canaanite inhabitants of the land saw the mourning on the threshing floor of Atad, they said, “This is a grievous mourning on the part of the Egyptians.” Therefore the place was named Abel-mizraim; it is beyond the Jordan.
