Genesis 50:9-11

King James Version

⁹ And there went up with him both chariots and horsemen: and it was a very great company.

¹⁰ And they came to the threshingfloor of Atad, which is beyond Jordan, and there they mourned with a great and very sore lamentation: and he made a mourning for his father seven days.

¹¹ And when the inhabitants of the land, the Canaanites, saw the mourning in the floor of Atad, they said, This is a grievous mourning to the Egyptians: wherefore the name of it was called Abelmizraim, which is beyond Jordan.
