Genesis 26 begins with a famine in the land and Isaac being directed by God to remain in Gerar and trust in Him for provision, rather than going down to Egypt. God reminds Isaac of the promises He made to his father to bless his descendants. So Isaac obeyed the Lord and stayed in Gerar, but he made the same mistake that Abraham twice made before. Rather than having faith in God, Isaac lies about his wife, saying she is his sister, in order to protect himself from any harm from other men in Gerar. The king, Abimelech, discovers the truth and becomes very angry and orders Isaac and his people to move away. Isaac had become very wealthy with his harvests, herds and flocks, so they moved away into the Valley of Gerar where they dug out and used the same water wells that Abraham had previously used. King Abimelech "saw clearly that the Lord was with Isaac" and made a treaty with him to avoid any future threats from Isaac's people.
