30 From thirty years old and upward even unto fifty years old shalt thou number them, all that enters into the host, to do work in the tabernacle of the testimony.
31 And this shall be the charge of their burden, according to all their service in the tabernacle of the testimony: the boards of the tabernacle and the bars thereof and the pillars thereof and sockets thereof,
32 and the pillars of the court round about and their sockets and their stakes and their cords with all their instruments and with all their service; and ye shall number by name the vessels of the charge of their burden.
33 This shall be the service of the families of the sons of Merari for all their ministry, in the tabernacle of the testimony, under the hand of Ithamar, the son of Aaron the priest.
34 So Moses and Aaron and the princes of the congregation numbered the sons of Kohath after their families and after the houses of their fathers,
35 from thirty years old and upward even unto fifty years old, all that enter into the host, to minister in the tabernacle of the testimony.
36 And those that were numbered of them by their families were two thousand seven hundred and fifty.
