Numbers 4:34 BBE

³²  And the pillars of the open space outside it, with their bases and their nails and cords and all the instruments used, and everything which has to be done there; all the instruments for which they are responsible are to be numbered by name.

³³  This is the work which the sons of Merari are to do in connection with the Tent of meeting, under the direction of Ithamar, the son of Aaron the priest.

³⁴  So Moses and Aaron and the chiefs of the people took in hand the numbering of the sons of the Kohathites, by families, in the order of their fathers' houses;

³⁵  Numbering all those from thirty to fifty years old who were able to do the work in the Tent of meeting;

³⁶  And the number of all these was two thousand, seven hundred and fifty.
