31And this is the charge of their burden, according to all their service in the tent of meeting; the boards of the tabernacle, and the bars thereof, and the pillars thereof, and the sockets thereof;

32and the pillars of the court round about, and their sockets, and their pins, and their cords, with all their instruments, and with all their service: and by name ye shall appoint the instruments of the charge of their burden.
