Numbers 34:1

“Command the children of Israel, and tell them, ‘When you come into the land of Canaan (this is the land that shall fall to you for an inheritance, even the land of Canaan according to its borders),

then your south quarter shall be from the wilderness of Zin along by the side of Edom, and your south border shall be from the end of the Salt Sea eastward.

Your border shall turn about southward of the ascent of Akrabbim, and pass along to Zin; and it shall pass southward of Kadesh Barnea; and it shall go from there to Hazar Addar, and pass along to Azmon.
