'Seed of Abraham' in the Bible

Art not thou our God, who didst drive out the inhabitants of this land before thy people Israel, and gavest it to the seed of Abraham thy friend for ever?

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

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

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