Stream of Egypt

(Isa. 27:12), the Wady el-'Arish, called also "the river of
Egypt," R.V., "brook of Egypt" (Num. 34:5; Josh. 15:4; 2 Kings
24:7). It is the natural boundary of Egypt. Occasionally in
winter, when heavy rains have fallen among the mountains inland,
it becomes a turbulent rushing torrent. The present boundary
between Egypt and Israel is about midway between el-'Arish
and Gaza.
