Ezra 6:19-22 - The Celebration Of Passover
19 And the children of Israel who came back kept the Passover on the fourteenth day of the first month. 20 the priests and the Levites made themselves clean together. They were all clean when they put the Passover lamb to death for all those who had come back, and for their brothers the priests and for themselves. 21 The children of Israel, who had come back, and all those who were joined to them, after separating themselves from the evil ways of the people of the land to become the servants of Jehovah, the God of Israel, ate together. 22 They joyfully kept the feast of unleavened bread for seven days. Jehovah filled them with joy by turning the heart of the king of Assyria to them to give them help in the work of the house of God, the God of Israel.
