2 Samuel 15:19-21
Then said the king to Ittai the Gittite, Wherefore goest thou also with us? return to thy place, and abide with the king: for thou art a stranger, and also an exile. Whereas thou camest but yesterday, should I this day make thee go up and down with us? seeing I go whither I may, return thou, and take back thy brethren: mercy and truth be with thee. And Ittai answered the king, and said, As the LORD liveth, and as my lord the king liveth, surely in what place my lord the king shall be, whether in death or life, even there also will thy servant be.
