John Gill's Exposition of the Bible
Genesis 50:11

And when the inhabitants of the land, the Canaanites
Who were at this time in the possession of the country where the threshingfloor of Atad was: when they saw the mourning in the floor of Atad;
for so large a company of people, and such a grand funeral procession, brought multitudes from all the neighbouring parts to see the sight; and when they observed the lamentation that was made, saw their mournful gestures and actions, and heard their doleful moan: they said, this is a grievous mourning to the Egyptians;
they concluded they must have lost some great man, to make such a lamentation for him: wherefore the name of it was called Abelmizraim, which is beyond
Jordan;
they changed the name of the place, and gave it another upon this occasion, which signifies the mourning of Egypt or of the Egyptians, they being the principal persons that used the outward and more affecting tokens of mourning; though the whole company might be taken for Egyptians by the Canaanites, because they came out of Egypt.
