Ezra 6:16-22 - Temple Dedication And The Passover
16 And the {Israelites}, the priests, the Levites, and the rest of the {returned exiles} celebrated the dedication of this house of God with joy. 17 And they offered during the dedication of this house of God one hundred young bulls, two hundred young rams, four hundred lambs, and twelve male goats as a sin offering for Israel [according to] the number of the tribes of Israel. 18 Then they set the priests in their divisions and the Levites in their sections for the work of God in Jerusalem, as it is written in the book of Moses.
19 On the fourteenth day of the first month the returned exiles observed the Passover feast. 20 For the priests and Levites together had consecrated themselves; all of them were clean. And they slaughtered the Passover sacrifice for all of the returned exiles, for their brothers the priests, and for themselves. 21 The {Israelites} who returned from the exile and all those who separated themselves from the uncleanness of the nations of the earth to seek Yahweh the God of Israel, ate. 22 With joy they celebrated the festival of unleavened bread [for] seven days, because Yahweh had made them joyful and had turned the heart of the king of Assyria toward them in order to help them with the work of their hands on the house of the God of Israel.
