Sihor Dictionary
Easton's Bible Dictionary (1897)
(correctly Shi’hor) black; dark the name given to the river Nile in Isa. 23:3; Jer. 2:18. In Josh. 13:3 it is probably “the river of Egypt”, i.e., the Wady el-Arish (1 Chr. 13:5), which flows “before Egypt”, i.e., in a north-easterly direction from Egypt, and enters the sea about 50 miles south-west of Gaza.
