Numbers 8:23-26

World English Bible

²³ Yahweh spoke to Moses, saying, ²⁴ “This is what is assigned to the Levites: from twenty-five years old and upward they shall go in to wait on the service in the work of the Tent of Meeting; ²⁵ and from the age of fifty years they shall retire from doing the work, and shall serve no more, ²⁶ but shall assist their brothers in the Tent of Meeting, to perform the duty, and shall perform no service. This is how you shall have the Levites do their duties.”
