'My Lord the King' in the Bible

And, now, let, I pray thee, my lord the king hear the words of his servant: if Jehovah hath moved thee against me, let Him accept a present; and if the sons of men -- cursed are they before Jehovah, for they have cast me out to-day from being admitted into the inheritance of Jehovah, saying, Go, serve other gods.

And David saith unto Achish, 'But what have I done? and what hast thou found in thy servant from the day that I have been before thee till this day -- that I go not in and have fought against the enemies of my lord the king?'
