²³ The Lord said to Moses, ²⁴ “This applies to the Levites: Men twenty-five years old or more^(A) shall come to take part in the work at the tent of meeting,^{(B) 25} but at the age of fifty,^(C) they must retire from their regular service and work no longer. ²⁶ They may assist their brothers in performing their duties at the tent of meeting, but they themselves must not do the work.^(D) This, then, is how you are to assign the responsibilities of the Levites.”
