Genesis 26:12-16

12And Isaac sowed in that land, and received in the same year a hundredfold; and Jehovah blessed him.

13And the man became great, and he became continually greater, until he was very great.

14And he had possessions of flocks, and possessions of herds, and a great number of servants; and the Philistines envied him.

15And all the wells that his father's servants had dug in the days of Abraham his father, the Philistines stopped them and filled them with earth.

16And Abimelech said to Isaac, Go from us; for thou art become much mightier than we.
