Numbers 8:22-26 And afterward the Levites went in to do their service in the tabernacle of the congregation, before Aaron and before his sons; as Jehovah commanded Moses concerning the Levites, so they did to them.

LITV⁽ⁱ⁾ ²² And afterward the Levites went in to do their service in the tabernacle of the congregation, before Aaron and before his sons; as Jehovah commanded Moses concerning the Levites, so they did to them. ²³ And Jehovah spoke to Moses, saying, ²⁴ This is that which pertains to the Levites: from twenty five years old and upward he shall go in to do the service and the works of the tabernacle of the congregation. ²⁵ And from a son of fifty years they shall return from the service of the work, and shall not serve any more. ²⁶ But he shall serve with his brothers in the tabernacle of the congregation, to keep the charge; only he shall not serve at a service. So you shall do to the Levites concerning their charge.
