On the fourteenth day of the first month the returned exiles kept the passover. For both the priests and the Levites had purified themselves; all of them were clean. So they killed the passover lamb for all the returned exiles, for their fellow priests, and for themselves. It was eaten by the people of Israel who had returned from exile, and also by all who had joined them and separated themselves from the pollutions of the nations of the land to worship the LORD, the God of Israel.
