'Seed of Abraham' in the Bible

Art not thou our God which didst cast out the inhabiters of this land before thy people Israel, and gavest it to the seed of Abraham thy lover forever?

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

And thou Israel, my servant; Jacob, my elect seed of Abraham my beloved,

Neither are they all children straightway because they are the seed of Abraham: But in Isaac shall thy seed be called,

I say then, Hath God cast away his people? God forbid. For even I verily am an Israelite of the seed of Abraham, and of the tribe of Benjamin;

They are Hebrews, so am I. They are Israelites, even so am I. They are the seed of Abraham, even so am I.

For he in no place taketh on him the angels: but the seed of Abraham taketh he on him.
