Numbers 8:23-26

Common English Bible

²³ The Lord spoke to Moses: ²⁴ This rule applies^[a] to the Levites: Everyone 25 years old and above will enter into service, performing the duties for the meeting tent. ²⁵ At 50 years old each will retire from service. They will perform their duties no longer. ²⁶ Each may assist his fellow Levites in the meeting tent with some responsibilities, but he may not perform service. This is how you should assign responsibilities to the Levites.
