'Grandfather' in the Bible

and the Lord stood at its top. He said, "I am the Lord, the God of your grandfather Abraham and the God of your father Isaac. I will give you and your descendants the ground you are lying on.

After all, there was no one in the entire house of my grandfather who did not deserve death from my lord the king. But instead you allowed me to eat at your own table! What further claim do I have to ask the king for anything?"
