Genesis 26:1-5, 12-17

Now, another famine struck the land, like the one in Abraham’s time. Isaac traveled to Gerar where Abimelech was the Philistine king. YAHWEH appeared before Isaac and said, “Do not go down to Egypt. Stay in the land that I will reveal to you. Live there as a foreigner, and my presence will be with you. I promise to bless you, for I will give all these lands to you and your descendants. I will fulfill the oath I swore to your father Abraham. I will make your descendants as numerous as the stars of heaven, and I will one day give them all these lands. I will bless all the nations of the earth through your offspring because Abraham was faithful to me. He listened to my voice and yielded his heart to follow my direction. He kept my commandments, my instructions, and my teachings.”

Isaac planted crops in that land, and in the same year reaped a hundred-fold harvest, for YAHWEH greatly blessed him! Isaac grew richer and richer until he was extremely wealthy. He acquired so many flocks and herds and so many servants that the Philistines grew jealous, so the Philistines stopped up all of Isaac’s wells and filled them with dirt—the same wells his father’s servants had dug in the time of Abraham. Eventually Abimelech’s jealousy got the better of him, and he said to Isaac, “You must leave us! You have become too rich and powerful for us!” So Isaac departed from Abimelech’s domain and camped near the Wadi of Gerar, where he settled.
