Thematic Bible: Band of gittites, attached to david

All his servants were leaving with him, along with all the Kerethites, all the Pelethites, and all the Gittites -- some six hundred men who had come on foot from Gath. They were leaving with the king. 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. 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!" read more.
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!" 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.
