Esdras 6:18

Y pusieron á los sacerdotes en sus clases, y á los Levitas en sus divisiones, sobre la obra de Dios que está en Jerusalem, conforme á lo escrito en el libro de Moisés.

And 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.
