'Seed of Abraham' in the Bible

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

O ye seed of Abraham his servant, ye sons of Jacob, his chosen.

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

then I will 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

I say therefore, did God thrust away his people? May it not happen! For I also am an Israelite from the seed of Abraham, of the tribe of Benjamin.

Are they Hebrews? I too. Are they Israelites? I too. Are they a seed of Abraham? I too.

For he certainly did not embrace heavenly agents, but he embraced the seed of Abraham.
