Numbers 4:29-33 - Duties Of The Merarites

²⁹ "And thou shalt number the sons of Merari in their kindreds and in the houses of their fathers - ³⁰ from thirty years and above unto fifty, all that is able to go forth in war - to do the service of the tabernacle of witness. ³¹ And this is the charge, that they must wait upon in all that they must serve in the tabernacle of witness: The boards of the dwelling, and the bars, pillars, and sockets thereof, ³² and the pillars of the court round about, and their sockets, pins and cords with all that pertaineth and serveth unto them. And by name ye shall reckon the things that they must wait upon to bear. ³³ This is the service of the kindreds of the sons of Merari in all their service in the tabernacle of witness by the hand of Ithamar the son of Aaron the priest."
