When the Canaanites who lived in the land saw them mourning at the threshing floor of Atad, they said, “This is a very sad occasion ¹  for the Egyptians.” That is why its name was called ²  Abel Mizraim, ³  which is beyond the Jordan.

When they came to the threshing floor of Atad ¹  on the other side of the Jordan, they mourned there with very great and bitter sorrow. ²  There Joseph observed a seven day period of mourning for his father.

So Esau hated ¹  Jacob because of the blessing his father had given to his brother. ²  Esau said privately, ³  “The time ⁴  of mourning for my father is near; then I will kill ⁵  my brother Jacob!”
