2 Samuel 15:16, 22-24

The king set out with everyone in his house, but he left ten slave women to take care of the palace.

David said to Ittai, “Go, march on.” So Ittai from Gath and all his people with their children marched on. All the people cried loudly as everyone passed by. King David crossed the Kidron Valley, and then all the people went on to the desert. Zadok and all the Levites with him carried the Ark of the Agreement with God. They set it down, and Abiathar offered sacrifices until all the people had left the city.
