1 Esdras 7:10
9. The priests also and the Levites stood arrayed in their vestments, according to their kindreds, in the service of the Lord God of Israel, according to the book of Moses: and the porters at every gate.10. And the children of Israel that were of the captivity held the passover the fourteenth day of the first month, after that the priests and the Levites were sanctified.11. They that were of the captivity were not all sanctified together: but the Levites were all sanctified together.
