Parallel
Genesis 50:11
Brenton's English Septuagint · Berean Standard Bible
And the inhabitants of the land of Chanaan saw the mourning at the floor of Atad, and said, This is a great mourning to the Egyptians; therefore he called its name, The mourning of Egypt, which is beyond Jordan.
When the Canaanites of the land saw the mourning at the threshing floor of Atad, they said, “This is a solemn ceremony of mourning by the Egyptians.” Thus the place across the Jordan is called Abel-mizraim (note: Abel-mizraim means mourning of the Egyptians.).
