Gerar
     a region; lodging-place, a very ancient town and district in the
     south border of Palestine, which was ruled over by a king named
     Abimelech (Gen. 10:19; 20:1, 2). Abraham sojourned here, and
     perhaps Isaac was born in this place. Both of these patriarchs
     were guilty of the sin of here denying their wives, and both of
     them entered into a treaty with the king before they departed to
     Beersheba (21:23-34; 26). It seems to have been a rich pastoral
     country (2 Chr. 14:12-18). Isaac here reaped an hundred-fold,
     and was blessed of God (Gen. 26:12). The "valley of Gerar" (Gen.
     26:17) was probably the modern Wady el-Jerdr.
