2 Samuel 15:19-22

15:19 Then the king said to Ittai the Gittite, “Why should you come with us? Go back and stay with the new king, for you are a foreigner and an exile from your own country. 15:20 It seems like you arrived just yesterday. Today should I make you wander around by going with us? I go where I must go. But as for you, go back and take your men with you. May genuine loyal love protect you!”

15:21 But Ittai replied to the king, “As surely as the Lord lives and as my lord the king lives, wherever my lord the king is, whether dead or alive, there I will be as well!” 15:22 So David said to Ittai, “Come along then.” So Ittai the Gittite went along, accompanied by all his men and all the dependents who were with him.
