Numbers 8:18-20

Complete Jewish Bible

¹⁸ But I have taken the L’vi’im in place of all the firstborn among the people of Isra’el, ¹⁹ and I have given the L’vi’im to Aharon and his sons from among the people of Isra’el to do the service of the people of Isra’el in the tent of meeting and to make atonement for the people of Isra’el, so that no plague will fall on the people of Isra’el in consequence of their coming too close to the sanctuary.”

²⁰ This is what Moshe, Aharon and all the community of the people of Isra’el did to the L’vi’im. The people of Isra’el acted in accordance with everything that Adonai had ordered Moshe in regard to the L’vi’im.
