Joshua 15:4

And they go out to Selmona, and issue at the valley of Egypt; and the termination of its boundaries shall be at the sea: these are their boundaries southward.

From thence it passed toward Azmon, and went out unto the river of Egypt; and the goings out of that coast were at the sea: this shall be your south coast.

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

From thence went it along to Azmon, and reached vnto the riuer of Egypt, and the end of that coast was on the Westside: this shall be your South coast.
