Context
30 you shall count them from thirty years old and upward even to fifty years old—everyone who enters on the service, to do the work of the Tent of Meeting.
31 This is the duty of their burden, according to all their service in the Tent of Meeting: the tabernacle’s boards, its bars, its pillars, its sockets,
32 the pillars of the court around it, their sockets, their pins, their cords, with all their instruments, and with all their service. You shall appoint the instruments of the duty of their burden to them by name.
