Numbers 18:2-4

Wycliffe Bible

² But also take thou with thee thy brethren of the lineage of Levi, and the sceptre, or power, of thy father, and be they ready, that they minister to thee. Forsooth thou and thy sons shall minister in the tabernacle of witnessing; (And also take with thee thy brothers from the tribe of Levi, thy father’s tribe, and be they ready to serve thee. But thou and thy sons shall minister in the Tabernacle of the Witnessing;)

³ and the deacons shall (stand) watch at thy commandments, and at all the works of the tabernacle; so only that they nigh not to the vessels of the saintuary, and to the altar, lest both they die, and ye, and (you all) perish together. (and the Levites shall do thy commands, and all their work in the Tabernacle; but they must not go near the vessels of the sanctuary, lest both they and ye die, and all of you perish together.)

⁴ Soothly be they with thee, and (stand) watch they in the keepings of the tabernacle, and in all the ceremonies thereof. An alien shall not be meddled with you. (Yea, be they with thee, and do their duties in the Tabernacle, and at all of its ceremonies. But do not let a foreigner, or a stranger, be mixed in with you.)
