Genesis 26:12-16

12And Isaac sowed in that land, and found in the same year a hundredfold: and Jehovah blessed him. 13And the man waxed great, and grew more and more until he became very great: 14and he had possessions of flocks, and possessions of herds, and a great household: and the Philistines envied him. 15Now all the wells which his father’s servants had digged in the days of Abraham his father, the Philistines had stopped, and filled with earth. 16And Abimelech said unto Isaac, Go from us; for thou art much mightier than we.
