Besor is formed by the water falling from the mountains of Idumea, and discharges itself into the Mediterranean, below Gaza. (Calmet)
Some take it to be the torrent of the desert, or the river of Egypt. Adrichomius makes it run from the mountains of Juda, so as to form the southern boundary of the tribe of Simeon. (Haydock)
