2 Samuel 15:19-21

19And the king said to Ittai the Gittite, Why dost thou also go with us? return to thy place, and abide with the king; for thou art a foreigner, and besides, thou hast emigrated to the place where thou [dwellest].

20Thou didst come yesterday, and should I this day make thee go up and down with us, seeing I go whither I can? Return and take back thy brethren. Mercy and truth be with thee!

21And Ittai answered the king and said, [As] Jehovah 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.
