'My Lord the King' in the Bible

And now be pleased to give ear, O my lord the king; let my prayer for help come before you, and do not make me go back to the house of Jonathan the scribe, for fear that I may come to my death there.

My lord the king, these men have done evil in all they have done to Jeremiah the prophet, whom they have put into the water-hole; and he will come to his death in the place where he is through need of food: for there is no more bread in the town.
