Numbers 18:5-7

Wycliffe Bible

⁵ (Stand) Watch ye in the keeping of the saintuary, and in the service of the altar, lest indignation rise upon the sons of Israel. (Do ye all your duties in the sanctuary, and in the service of the altar, lest indignation rise upon the Israelites.)

⁶ Lo! I have given to you your brethren, the deacons, from the midst of the sons of Israel, and I have given you them (as) a free gift to the Lord, that they serve in the services of the tabernacle. (Lo! I have given you your brothers, the Levites, from among the Israelites, and I have given them to you as a free gift for the Lord, in their service to the Tabernacle.)

⁷ Soothly thou and thy sons, keep your priesthood; and all things that pertain to the adorning of the altar, and be within the veil, shall be ministered by [the] priests; if any stranger nigheth thereto, he shall be slain. (Thou and thy sons, do your priestly duties; and all the things in the service of the altar, and that be within the Veil, shall be the priests’ responsibility; if any stranger nigheth thereto, he shall be put to death.)
