Ezra 6:18-20

Complete Jewish Bible

¹⁸ Then they installed the cohanim in their divisions and the L’vi’im in their orders for the service of God in Yerushalayim, as written in the book of Moshe.

¹⁹ The people from the exile kept Pesach on the fourteenth day of the first month. ²⁰ For the cohanim and L’vi’im had purified themselves together; all of them were pure. So they slaughtered the Pesach lambs for all the people from the exile and for their kinsmen the cohanim and for themselves.
