Genesis 26:14-17

26:14 For he had possession of flocks, and possession of herds, and great store of servants: and the Philistines envied him. 26:15 For all the wells which his father’s servants had digged in the days of Abraham his father, the Philistines had stopped them, and filled them with earth. 26:16 And Abimelech said unto Isaac, Go from us; for thou art much mightier than we. 26:17 And Isaac departed thence, and pitched his tent in the valley of Gerar, and dwelt there.
