Ezra 6:20-22

Complete Jewish Bible

²⁰ For the cohanim and L’vi’im had purified themselves together; all of them were pure. So they slaughtered the Pesach lambs for all the people from the exile and for their kinsmen the cohanim and for themselves. ²¹ The people of Isra’el who had returned from the exile and all those who had renounced the filthy practices of the nations living in the land in order to seek Adonai the God of Isra’el, ate [the Pesach lamb] ²² and joyfully kept the feast of matzah for seven days; for Adonai had filled them with joy by turning the heart of the king of Ashur toward them, so that he assisted them in the work of the house of God, the God of Isra’el.
