Isaac because of famine goeth to Gerar. God instructeth and blesseth him. He denieth his wife, and is reproved by Abimelech. He groweth rich, and the Philistines envy him. He diggeth sundry wells. God appeareth to him in Beer-sheba, and blesseth him. Abimelech maketh a covenant with him there. Esau's Canaanitish wives are a grief to his parents.
