Numbers 34:5

And the border shall fetch a compass
Not go on in a straight line, but turn about:

from Azmon unto the river of Egypt;
the river Nile, as both the Targums of Jonathan and Jerusalem; but Aben Ezra seems to deny that that river is meant: and some think that Rhinocolura, which flows into the Mediterranean sea, is meant; or the "valley of Egypt", Casiotis, which divided Judea from Egypt, as follows:

and the goings out of it;
not of the river, but of the border:

shall be at the sea;
the above sea, called in the next verse the great sea; all the Targums render it to the west.
