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 you, too, are an exile from your own country.
You came only yesterday, and today shall I have you wander off with us wherever I have to go? Return and take your brothers with you, and may the Lord show you kindness and fidelity.”
David then divided the troops three ways, a third under Joab, a third under Abishai, son of Zeruiah and brother of Joab, and a third under Ittai the Gittite. The king said to the troops, “I intend to go out with you myself.”
