Numbers 3:36-38

New Revised Standard Version, Anglicised

³⁶ The responsibility assigned to the sons of Merari was to be the frames of the tabernacle, the bars, the pillars, the bases, and all their accessories—all the service pertaining to these; ³⁷ also the pillars of the court all around, with their bases and pegs and cords.

³⁸ Those who were to camp in front of the tabernacle on the east—in front of the tent of meeting towards the east—were Moses and Aaron and Aaron’s sons, having charge of the rites within the sanctuary, whatever had to be done for the Israelites; and any outsider who came near was to be put to death.
