Shihor in the Bible

from the Shihor, which is before Egypt, even unto the border of Ekron northward, which is reckoned to the Canaanites; the five lords of the Philistines; the Gazites, and the Ashdodites, the Ashkelonites, the Gittites, and the Ekronites; also the Avvim,

and Allammelech, and Amad, and Mishal; and it reached to Carmel westward, and to Shihor-libnath;

So David gathered all Israel together, from Shihor of Egypt even unto the entering of Hemath, to bring the ark of God from Kirjathjearim.

And on great waters the seed of the Shihor, the harvest of the Nile, was her revenue; and she was the mart of nations.

And now what hast thou to do in the way to Egypt, to drink the waters of the Shihor? or what hast thou to do in the way to Assyria, to drink the waters of the River?
