The Brook of Egypt is the name used in some English translations of the Bible for the Hebrew Nachal Mitzrayim ("River of Egypt") used for the river defining the westernmost border of the Land of Israel. Popular Bible commentaries identify it with Wadi El-Arish although the identification is problematic. Early Aramaic translations and Jewish commentaries identify it with the Pelusian arm of the Nile—a no longer extant branch of the Nile lying on the border of Ancient Egypt. The Besor has also been proposed as an identification.
