12Then Isaac sowed in that land, and received in the same year an hundredfold: and the LORD blessed him. 13And the man waxed great, and went forward, and grew until he became very great: 14For he had possession of flocks, and possession of herds, and great store of servants: and the Philistines envied him. 15For 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.16And Abimelech said unto Isaac, Go from us; for thou art much mightier than we. 17And Isaac departed thence, and pitched his tent in the valley of Gerar, and dwelt there. 18And Isaac digged again the wells of water, which they had digged in the days of Abraham his father; for the Philistines had stopped them after the death of Abraham: and he called their names after the names by which his father had called them.
