'Descendants Of Abraham' in the Bible

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

then I would [also] 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.

For, as we all know, He (Christ) does not take hold of [the fallen] angels [to give them a helping hand], but He does take hold of [the fallen] descendants of Abraham [extending to them His hand of deliverance].
