Genesis 50:10-11

10They came to Atad's threshing floor, near the Jordan River. They stayed there for seven days to weep for the death of Jacob. They were very sad.

11The Canaanite people who lived near there saw how sad Joseph and his people were. So they gave Atad's threshing floor a different name. They called it ‘Abel Mizraim’. They said, ‘The Egyptians are showing that they are very sad because an important person has died.’
