'Seed of Abraham' in the Bible

Did you not, our God, drive out the inhabitants of this land before your people Israel, and give it to the seed of Abraham your friend forever?

you seed of Abraham, his servant, you children of Jacob, his chosen ones.

"But you, Israel, my servant, Jacob whom I have chosen, the seed of Abraham my friend,

then will I also cast away the seed of Jacob, and of David my servant, so that I will not take of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and will have mercy on them.'"

Are they Hebrews? So am I. Are they Israelites? So am I. Are they the seed of Abraham? So am I.

For, truly, he did not come to help the angels, but to help the seed of Abraham.
