2 Samuel 15:18-19

And all his servants are passing on at his side, and all the Cherethite, and all the Pelethite, and all the Gittites, six hundred men who came at his feet from Gath, are passing on at the front of the king.

And the king saith unto Ittai the Gittite, `Why dost thou go--thou also--with us? turn back--and abide with the king, for thou art a stranger, and also an exile thou--to thy place.
