'Descendants Of Abraham' in the Bible

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

then I would reject the descendants of Jacob and David My servant, not taking from his descendants rulers over the descendants of Abraham, Isaac and Jacob. But I will restore their fortunes and will have mercy on them.’”

Are they Hebrews? So am I. Are they Israelites? So am I. Are they descendants of Abraham? So am I.
