Numbers 34:3-6

3Then your south side shall be from the wilderness of Zin alongside of Edom, and your southern border shall be from the end of the salt sea eastward;

4and your border shall turn from the south of the ascent of Akrabbim, and pass on to Zin, and shall end southward at Kadesh-barnea, and shall go on to Hazar-Addar, and pass on to Azmon.

5And the border shall turn from Azmon unto the torrent of Egypt, and shall end at the sea.

6And as west border ye shall have the great sea, and [its] coast. This shall be your west border.
