2 Samuel 15:18-22

All of David’s servants passed on beside him, and all the Cherethites, Pelethites and the Gittites, six hundred men who had come with him from Gath, passed on before the king. Then the king said to Ittai the Gittite, “Why should you go with us, too? Go back and stay with the king [of your own country], for you are a foreigner and an exile as well; return to your own place. You came only yesterday, so should I make you wander with us today while I go where I will? Return and take your brothers back with you also. May lovingkindness and faithfulness be with you.” But Ittai answered the king, “As the LORD lives, and as my lord the king lives, most certainly wherever my lord the king may be, whether for death or life, there will your servant be also.” So David said to Ittai, “Go on and cross over [the Brook Kidron].” So Ittai the Gittite crossed over with all his men and all the little ones who were with him.
