Numbers 34:1-3

Then the Lord spoke to Moses, saying,

“Command the sons of Israel and say to them, ‘When you enter the land of Canaan, this is the land that shall fall to you as an inheritance, that is, the land of Canaan according to its borders.

Your southern region shall extend from the wilderness of Zin along the side of Edom, and your southern border shall extend from the end of the Salt Sea eastward.
