Genesis 26:3

But God said, “No, but Sarah your wife will bear you a son, and you shall call his name Isaac; and I will establish My covenant with him for an everlasting covenant for his seed after him.

Now it happened after the death of Abraham, that God blessed his son Isaac; and Isaac lived by Beer-lahai-roi.

And Isaac sowed in that land and reaped in the same year one hundredfold. And Yahweh blessed him,

And Yahweh appeared to him that night and said, “I am the God of your father Abraham; Do not fear, for I am with you. I will bless you and multiply your seed, For the sake of My servant Abraham.”

And behold, Yahweh stood above it and said, “I am Yahweh, the God of your father Abraham and the God of Isaac; the land on which you lie, I will give it to you and to your seed.

“Behold, I am with you and will keep you wherever you go. And I will bring you back to this land; for I will not forsake you until I have done what I have promised you.”

“And the land which I gave to Abraham and Isaac, I will give it to you, And I will give the land to your seed after you.”

Then Israel said to Joseph, “Behold, I am about to die, but God will be with you and will bring you back to the land of your fathers.

And Joseph said to his brothers, “I am about to die, but God will surely take care of you and bring you up from this land to the land which He swore to Abraham, to Isaac, and to Jacob.”

So God heard their groaning; and God remembered His covenant with Abraham, Isaac, and Jacob.

“And I also established My covenant with them, to give them the land of Canaan, the land in which they sojourned.

‘And I will bring you to the land which I swore to give to Abraham, to Isaac, and to Jacob, and I will give it to you for a possession; I am Yahweh.’”

Then Yahweh spoke to Moses, “Go! Go up from here, you and the people whom you have brought up from the land of Egypt, to the land of which I swore to Abraham, to Isaac, and to Jacob, saying, ‘To your seed I will give it.’

then I will remember My covenant with Jacob, and I will remember also My covenant with Isaac and My covenant with Abraham as well, and I will remember the land.

‘See, I have given over the land before you; go in and possess the land which Yahweh swore to give to your fathers, to Abraham, to Isaac, and to Jacob, to them and to their seed after them.’

Then Yahweh said to him, “This is the land which I swore to Abraham, to Isaac, and to Jacob, saying, ‘I will give it to your seed’; I have let you see it with your eyes, but you shall not go over there.”

Which He cut with Abraham, And His oath to Isaac.
