Numbers 34:3, 6, 9-10

your south side shall be from the wilderness of Zin alongside Edom, and your southern border shall run from the end of the Salt Sea on the east.

“For the western border, you shall have the Great Sea and its coast. This shall be your western border.

Then the border shall extend to Ziphron, and its limit shall be at Hazar-enan. This shall be your northern border. “You shall draw a line for your eastern border from Hazar-enan to Shepham.
