Joshua 15:4
Brenton's English Septuagint · Berean Standard Bible
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.
It proceeded to Azmon, joined the Brook of Egypt, and ended at the Sea (note: That is, the Mediterranean Sea, also called the Great Sea; also in verses 11, 12, and 47). This was their (note: LXX; Hebrew your) southern border.
