2 Samuel 15:20-21

20It seems like only a few days since you arrived here. There is no reason for you to travel with us. I do not even know where we are going! So you should go back. Take your men with you. I pray that the Lord will keep you safe with his faithful love.’

21But Ittai replied to the king, ‘As surely as the Lord lives and as surely as you live, I promise that I will go with you, sir. Wherever you go, I will be there with you. My lord the king, I will stay with you, even if it brings death.’
