2 Samuel 15:20-21

20In fact, you came only yesterday. Should I make you wander up and down with us today, since I go I know not where? Return, and take your brethren back. Mercy and truth be with you.”

21But Ittai answered the king and said, “As the Lord lives, and as my lord the king lives, surely in whatever place my lord the king shall be, whether in death or life, even there also your servant will be.”
