³¹ And their charge shall be the ark, and the table, and the candlestick, and the altars, and the vessels of the sanctuary wherewith they minister, and the screen, and all the service thereof. ³² And Eleazar the son of Aaron the priest shall be prince of the princes of the Levites, and have the oversight of them that keep the charge of the sanctuary.
