1 Esdras 1:9-19

9 And Jeconiah and Shemaiah and Nethanel his brother, and Hashabiah and Ochiel and Joram, captains over thousands, gave the Levites for the passover five thousand sheep and seven hundred calves.
10 And this is what took place. The priests and the Levites, properly arrayed and having the unleavened bread, stood according to kindred
11 and the grouping of the fathers' houses, before the people, to make the offering to the Lord as it is written in the book of Moses; this they did in the morning.
12 They roasted the passover lamb with fire, as required; and they boiled the sacrifices in brass pots and caldrons, with a pleasing odor,
13 and carried them to all the people. Afterward they prepared the passover for themselves and for their brethren the priests, the sons of Aaron,
14 because the priests were offering the fat until night; so the Levites prepared it for themselves and for their brethren the priests, the sons of Aaron.
15 And the temple singers, the sons of Asaph, were in their place according to the arrangement made by David, and also Asaph, Zechariah, and Eddinus, who represented the king.
16 The gatekeepers were at each gate; no one needed to depart from his duties, for their brethren the Levites prepared the passover for them.
17 So the things that had to do with the sacrifices to the Lord were accomplished that day: the passover was kept
18 and the sacrifices were offered on the altar of the Lord, according to the command of King Josiah.
19 And the people of Israel who were present at that time kept the passover and the feast of unleavened bread seven days.
