1 Esdras 1:14-16

Revised Standard Version

¹⁴ because the priests were offering the fat until night; so the Levites prepared it for themselves and for their brethren the priests, the sons of Aaron. ¹⁵ And the temple singers, the sons of Asaph, were in their place according to the arrangement made by David, and also Asaph, Zechari′ah, and Eddinus, who represented the king. ¹⁶ The gatekeepers were at each gate; no one needed to depart from his duties, for their brethren the Levites prepared the passover for them.
