Genesis 26:12-17
26:12 When Isaac planted in that land, he reaped in the same year a hundred times what he had sown, because the Lord blessed him.
26:13 The man became wealthy. His influence continued to grow until he became very prominent.
26:14 He had so many sheep and cattle and such a great household of servants that the Philistines became jealous of him.
26:15 So the Philistines took dirt and filled up all the wells that his father’s servants had dug back in the days of his father Abraham.
26:16 Then Abimelech said to Isaac, “Leave us and go elsewhere, for you have become much more powerful than we are.”
26:17 So Isaac left there and settled in the Gerar Valley.
