1 Esdras 1:3-7
3 And he spake unto the Levites, the holy ministers of Israel, that they should hallow themselves unto the Lord, to set the holy ark of the Lord in the house that king Solomon the son of David had built:
4 And said, Ye shall no more bear the ark upon your shoulders: now therefore serve the Lord your God, and minister unto his people Israel, and prepare you after your families and kindreds,
5 According as David the king of Israel prescribed, and according to the magnificence of Solomon his son: and standing in the temple according to the several dignity of the families of you the Levites, who minister in the presence of your brethren the children of Israel,
6 Offer the passover in order, and make ready the sacrifices for your brethren, and keep the passover according to the commandment of the Lord, which was given unto Moses.
7 And unto the people that was found there Josias gave thirty thousand lambs and kids, and three thousand calves: these things were given of the king's allowance, according as he promised, to the people, to the priests, and to the Levites.
