Ezra 6:16-22 - Temple Dedication And The Passover
16 And the sons of Israel, the priests and the Levites and the rest of the sons of the exile, made the consecration of this house of God in gladness. 17 And they brought near to the consecration of this house of God a hundred oxen, two hundred rams, four hundred lambs; and he goats of the goats for sin, for all Israel twelve, for the number of the tribes of Israel. 18 And they set up the priests in their division, and the Levites in their classes, for the work of God which is in Jerusalem; according to the writing of the book of Moses.
19 And the sons of the exile will do the passover in the fourteenth to the first month. 20 For the priests and Levites were purified as one, all of them being purified; and they will slaughter the pass-over for all the sons of the exile, and for their brethren the priests, and for themselves. 21 And the sons of Israel will eat; those turning back from exile and every one being separated from the uncleanness of the nations of the earth to them, to seek for Jehovah the God of Israel; 22 And they will do the festival of the unleavened seven days in gladness: for Jehovah gladdened them, and turned the heart of the king of Assur to them, to strengthen their hands in the work of the house of God, the God of Israel
