2 Samuel 15:16-18, 22-24

So the king and his entire household escaped on foot. The king left ten concubines behind to tend to the palace. And so they left, step by step by step, and then paused at the last house as the whole army passed by him—all the Kerethites, all the Pelethites, and the six hundred Gittites who had marched with him from Gath, went past.

“All right,” said David, “go ahead.” And they went on, Ittai the Gittite with all his men and all the children he had with him. The whole country was weeping in loud lament as all the people passed by. As the king crossed the Brook Kidron, the army headed for the road to the wilderness. Zadok was also there, the Levites with him, carrying GOD’s Chest of the Covenant. They set the Chest of God down, Abiathar standing by, until all the people had evacuated the city.
