Numbers 8:24-26

New Life Version

²⁴ “This is the rule for the Levites. Those who are twenty-five years old and older will go in to do the work of the meeting tent. ²⁵ But when they are fifty years old they will stop these duties and not work any more. ²⁶ They may help their brothers in the meeting tent to do what needs to be done but they themselves must not do the work. These are the rules for the Levites when giving them their duties.”
