Numbers 34:5

The border of the Canaanite extended from Sidon as you go toward Gerar, as far as Gaza; as you go toward Sodom and Gomorrah and Admah and Zeboiim, as far as Lasha.

On that day Yahweh cut a covenant with Abram, saying, “To your seed I have given this land, From the river of Egypt as far as the great river, the river Euphrates:

And it passed on to Azmon and went out to the brook of Egypt, and the border ended at the sea. This shall be your south border.

So Solomon celebrated the feast at that time, and all Israel with him, a great assembly from Lebo-hamath to the brook of Egypt, before Yahweh our God, for seven days and seven more days, even fourteen days.

Thus says Lord Yahweh, “This shall be the boundary by which you shall apportion the land for an inheritance among the twelve tribes of Israel; Joseph shall have two portions.

“And the south side toward the south shall extend from Tamar as far as the waters of Meribath-kadesh, to the brook of Egypt and to the Great Sea. This is the south side toward the south.
