Smith’s Bible Dictionary

Gerar

(a lodging-place), a very ancient city south of Gaza. It occurs chiefly in Genesis, (Genesis 10:19; 20:1; 26:17) also incidentally in (2 Chronicles 14:13,14) It must have trenched on the "south" or "south country" of later Palestine. From a comparison of (Genesis 21:32) with Genesis26:23,26 Beersheba would seem to be just on the verge of this territory, and perhaps to be its limit towards the northeast.
