'Descendants' in the Bible

Has not the scripture said that the Christ comes from the descendants of David, and from Bethlehem, the village where David was?"

They replied to him, "We are descendants of Abraham and have not been enslaved to anyone at any time. How do you say, 'You will become free'?"

I know that you are descendants of Abraham. But you are seeking to kill me, because my word makes no progress among you.
