Genesis 50:9 (KJV)

And Joseph went up to bury his father: and with him went up all the servants of Pharaoh, the elders of his house, and all the elders of the land of Egypt,

And all the house of Joseph, and his brethren, and his father’s house: only their little ones, and their flocks, and their herds, they left in the land of Goshen.

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

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.

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 Abel–mizraim, which is beyond Jordan.
