Isaac went unto Abimelech— The Abimelech here mentioned, is thought by some to have been the son of him to whom Abraham went, Abimelech being, as we have observed, a common name of the kings of Palestine; but as the same friend (viz. Phichol the chief captain) Genesis 26:26 is mentioned as in ch. Genesis 21:22. it is not unlikely that it was the same king.
