Lot looked around and noticed that the whole Jordan plain as far as Zoar was well-watered like the garden of the LORD or like the land of Egypt. (This was before the LORD destroyed Sodom and Gomorrah.)

So Lot chose for himself all the Jordan plain. Then Lot traveled eastward, and they separated from each other.

When they arrived at Atad's threshing floor, which is located beyond the Jordan River, they held a great and mournful memorial service, during which Joseph spent seven days mourning for his father.

As soon as the Canaanites who lived in the land observed the mourning going on at Atad's threshing floor, they commented "This is a significant time of mourning for the Egyptians." That's why the place, which is located beyond the Jordan River, became known as Abel-mizraim.
