'Stream' in the Bible

And the south side to the south will be from Tamar as far as the waters of Meribath-kadesh, to the stream of Egypt, to the Great Sea. This is the south side, on the south.

And on the limit of Gad, on the south side and to the south of it, the limit will be from Tamar to the waters of Meribath-kadesh, to the stream, to the Great Sea.
