Genesis Chapter 26

26:4-10
And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed;
Because that Abraham obeyed my voice, and kept my charge, my commandments, my statues, and my laws.
And Isaac dwelt in Gerar:
And the men of the place asked him of his wife; and he said, She is my sister: for he feared to say, She is my wife; lest, said he, the men of the place should kill me for Rebekah; because she was fair to look upon.
And it came to pass, when he had been there a long time, that Abimelech king of the Philistines looked out at a window, and saw, and, behold, Isaac was sporting with Rebekah his wife.
And Abimelech called Isaac, and said, Behold, of a surety she is thy wife: and how saidst thou, She is my sister? And Isaac said unto him, Because I said, Lest I die for her.
And Abimelech said, What is this thou hast done unto us? one of the people might lightly have lain with thy wife, and thou shouldest have brought guiltiness upon us.

26:14-16
For he had possession of flocks, and possession of herds, and great store of servants: and the Philistines envied him.
For all the wells which his father's servants had digged in the days of Abraham his father, the Philistines had stopped them, and filled them with earth.
And Abimelech said unto Isaac, Go from us; for thou art much mightier than we.

26:19
And Isaac's servants digged in the valley, and found there a well of springing water.

26:24
And the Lord appeared unto him the same night, and said, I am the God of Abraham thy father: fear not, for I am with thee, and will bless thee, and multiply thy seed for my servant Abraham's sake
