1 Esdras 1:4-6

New Revised Standard Version, Anglicised

⁴ and he said, ‘You need no longer carry it on your shoulders. Now worship the Lord your God and serve his people Israel; prepare yourselves by your families and kindred, ⁵ in accordance with the directions of King David of Israel and the magnificence of his son Solomon. Stand in order in the temple according to the groupings of the ancestral houses of you Levites, who minister before your kindred the people of Israel, ⁶ and kill the passover lamb and prepare the sacrifices for your kindred, and keep the passover according to the commandment of the Lord that was given to Moses.’
