Genesis 26:1 NKJV

“There was a famine in the land, besides the first famine that was in the days of Abraham. And Isaac went to Abimelech king of the Philistines, in Gerar.”

Genesis 26:2-5, 12-13 NKJV

“Then the LORD appeared to him and said: “Do not go down to Egypt; live in the land of which I shall tell you. Dwell in this land, and I will be with you and bless you; for to you and your descendants I give all these lands, and I will perform the oath which I swore to Abraham your father. And I will make your descendants multiply as the stars of heaven; I will give to your descendants all these lands; and in your seed all the nations of the earth shall be blessed; because Abraham obeyed My voice and kept My charge, My commandments, My statutes, and My laws.”

Then Isaac sowed in that land, and reaped in the same year a hundredfold; and the LORD blessed him. The man began to prosper, and continued prospering until he became very prosperous
