'God Forbid' in the Bible

And he said to him, God forbid; thou shalt not die: behold, my father will do nothing either great or small, and not apprise me; and why should my father hide this thing from me? it is not so.

And he said, My God forbid it me, that I should do this thing! should I drink the blood of these men who went at the risk of their lives? for at the risk of their lives they brought it. Therefore he would not drink it. These things did the three mighty men.
