Joshua 15:4, 47
Joshua 15:4 NKJV
From there it passed toward Azmon and went out to the Brook of Egypt; and the border ended at the sea. This shall be your southern border.
Joshua 15:47 NKJV
Ashdod with its towns and villages, Gaza with its towns and villages—as far as the Brook of Egypt and the Great Sea with its coastline.
