Dark, (1 Chr. 13:5), the southwestern boundary of Canaan, the Wady el-‘Arish. (See SIHOR; NILE.)
Shihor
Where did the land end on the south? Scripture answers with a river named Shihor, or Sihor, “which is before Egypt.” Joshua uses it as a boundary marker, and David gathered all Israel “from Shihor of Egypt even unto the entering of Hemath” to bring the ark of God from Kirjathjearim. Isaiah speaks of “the seed of Sihor, the harvest of the river,” and Jeremiah asks what Israel has to do with the way of Egypt, “to drink the waters of Sihor.” It is a watercourse that marks the edge of one country and the start of another. Joshua 13 and 1 Chronicles 13 are the places to begin.
