I Esdras 7:9-15

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.
12 And so they offered the passover for all them of the captivity, and for their brethren the priests, and for themselves.
13 And the children of Israel that came out of the captivity did eat, even all they that had separated themselves from the abominations of the people of the land, and sought the Lord.
14 And they kept the feast of unleavened bread seven days, making merry before the Lord,
15 For that he had turned the counsel of the king of Assyria toward them, to strengthen their hands in the works of the Lord God of Israel.
