Genesis 26:11-15

So Abimelech commanded all the people, saying, “He who touches this man or his wife will certainly be put to death.”

Now Isaac sowed in that land and reaped in the same year a hundred times as much. And the Lord blessed him,

and the man became rich, and continued to grow richer until he became very wealthy;

for he had possessions of flocks and herds, and a great household, so that the Philistines envied him.

Now all the wells which his father’s servants had dug in the days of his father Abraham, the Philistines stopped up by filling them with dirt.
