After a sojourn of twenty-six years in the land of the Philistines, Abraham departed thence, and he settled in the neighborhood of Hebron. There he was visited by Abimelech with twenty of his grandees, who requested him to make an alliance with the Philistines.
As long as Abraham was childless, the heathen did not believe in his piety, but when Isaac was born, they said to him, "God is with thee." But again they entertained doubt of his piety when he cast off Ishmael. They said, "Were he a righteous man, he would not drive his first-born forth from his house." But when they observed the impious deeds of Ishmael, they said, "God is with thee in all thou doest." That Abraham was the favorite of God, they saw in this, too, that although Sodom was destroyed and all traffic had come to a standstill in that region, yet Abraham's treasure chambers were filled. For these reasons, the Philistines sought to form an alliance with him, to remain in force for three generations to come, for it is to the third generation that the love of a father extends.
