Ezra 6:19-22 - The Celebration Of Passover
19 And the sons of the captivity kept the Passover on the fourteenth of the first month. 20 For the priests and the Levites were purified together, all of them pure. And they slaughtered the passover lamb for all the sons of the captivity, and for their brothers the priests, and for themselves. 21 And the sons of Israel ate, all who had come again out of captivity, and all such as had separated themselves to them from the uncleanness of the nations of the land, in order to seek Jehovah, the God of Israel. 22 And they kept the Feast of Unleavened Bread seven days with joy. For Jehovah had made them joyful, and had turned the heart of the king of Assyria to them, to make their hands strong in the work of the house of God, the God of Israel.
