'Impute' in the Bible

Did I then begin to inquire of God for him? be it far from me: let not the king impute any thing unto his servant, nor to all the house of my father: for thy servant knew nothing of all this, less or more.

And said unto the king, Let not my lord impute iniquity unto me, neither do thou remember that which thy servant did perversely the day that my lord the king went out of Jerusalem, that the king should take it to his heart.

Blessed is the man to whom the Lord will not impute sin.
