Numbers 3:38-39

English Standard Version

³⁸ Those who were to camp before the tabernacle on the east, before the tent of meeting toward the sunrise, were Moses and Aaron and his sons, ^(A)guarding the sanctuary itself, to protect^[a] the people of Israel. And any outsider who came near was to be put to death. ³⁹ All those listed among the Levites, whom Moses and Aaron listed at the commandment of the Lord, by clans, all the males from a month old and upward, were ^(B)22,000.
