2 Samuel 15:19-22

19Then the king said to Ittai the Gittite, “Why should you also go with us? Go back and stay with the king, for you are a foreigner and also an exile from your own place.

20Your arrival was only yesterday—should I make you wander around with us today, to go wherever I may go? Go back and take your kinsmen back with you. Kindness and truth be with you!”

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

22So David said to Ittai, “Go on and cross over.” So Ittai the Gittite passed on, with all his men and all the little children who were with him.
