Genesis 25:23

25:23 and the Lord said to her,

“Two nations are in your womb,

and two peoples will be separated from within you.

One people will be stronger than the other,

and the older will serve the younger.”

Genesis 27:27-30

27:27 So Jacob went over and kissed him. When Isaac caught the scent of his clothing, he blessed him, saying,

“Yes, my son smells

like the scent of an open field

which the Lord has blessed.

27:28 May God give you

the dew of the sky

and the richness of the earth,

and plenty of grain and new wine.

27:29 May peoples serve you

and nations bow down to you.

You will be lord over your brothers,

and the sons of your mother will bow down to you.

May those who curse you be cursed,

and those who bless you be blessed.”

27:30 Isaac had just finished blessing Jacob, and Jacob had scarcely left his father’s presence, when his brother Esau returned from the hunt.

Genesis 27:33

27:33 Isaac began to shake violently and asked, “Then who else hunted game and brought it to me? I ate all of it just before you arrived, and I blessed him. He will indeed be blessed!”

Genesis 28:3-4

28:3 May the sovereign God bless you! May he make you fruitful and give you a multitude of descendants! Then you will become a large nation. 28:4 May he give you and your descendants the blessing he gave to Abraham so that you may possess the land God gave to Abraham, the land where you have been living as a temporary resident.”

Genesis 28:13-14

28:13 and the Lord stood at its top. He said, “I am the Lord, the God of your grandfather Abraham and the God of your father Isaac. I will give you and your descendants the ground you are lying on. 28:14 Your descendants will be like the dust of the earth, and you will spread out to the west, east, north, and south. All the families of the earth will pronounce blessings on one another using your name and that of your descendants.

Genesis 32:28-30

32:28 “No longer will your name be Jacob,” the man told him, “but Israel, because you have fought with God and with men and have prevailed.”

32:29 Then Jacob asked, “Please tell me your name.” “Why do you ask my name?” the man replied. Then he blessed Jacob there. 32:30 So Jacob named the place Peniel, explaining, “Certainly I have seen God face to face and have survived.”

Genesis 48:4

48:4 He said to me, ‘I am going to make you fruitful and will multiply you. I will make you into a group of nations, and I will give this land to your descendants as an everlasting possession.’

Romans 9:10-13

9:10 Not only that, but when Rebekah had conceived children by one man, our ancestor Isaac – 9:11 even before they were born or had done anything good or bad (so that God’s purpose in election would stand, not by works but by his calling) – 9:12 it was said to her, “The older will serve the younger,” 9:13 just as it is written: “Jacob I loved, but Esau I hated.”
