Isaac became extremely wealthy. He also re-dug some of the wells that his father Abraham had dug, but had since been stopped up by the Philistines. The Philistines eventually became envious of his wealth, and asked him to leave. Isaac complied, moving away from the city and settling in the Gerar Valley. There, Isaac's servants dug two new wells but the Philistines contested his ownership over these wells. The third well he dug was uncontested.
