'Common' in the Bible

But the king said, "What do we have in common, you sons of Zeruiah? If he curses because the Lord has said to him, 'Curse David!', who can say to him, 'Why have you done this?'"

But David said, "What do we have in common, you sons of Zeruiah? You are like my enemy today! Should anyone be put to death in Israel today? Don't you realize that today I am king over Israel?"
