'Far Be It from Me' in the Bible

As far as I am concerned, far be it from me to sin against the Lord by ceasing to pray for you! I will instruct you in the way that is good and upright.

Was it just today that I began to inquire of God on his behalf? Far be it from me! The king should not accuse his servant or any of my father's house. For your servant is not aware of all this -- not in whole or in part!"
