'Descendants' in the Bible

Don't think you can say to yourselves, "We have father Abraham!' because I tell you that God can raise up descendants for Abraham from these stones!

saying, "Teacher, Moses said if someone dies without having children, his brother is to marry his wife and {father} descendants for his brother.

Now there were seven brothers with us. And the first died [after] getting married, and [because he] did not have descendants, he left his wife to his brother.

Therefore, you testify against yourselves that you are descendants of those who murdered the prophets.
