Ezra 6:18-20

World English Bible

¹⁸ They set the priests in their divisions, and the Levites in their courses, for the service of God, which is at Jerusalem, as it is written in the book of Moses.

¹⁹ The children of the captivity kept the Passover on the fourteenth day of the first month. ²⁰ Because the priests and the Levites had purified themselves together, all of them were pure. They killed the Passover for all the children of the captivity, for their brothers the priests, and for themselves.
