2 Chronicles 35:14-16

Darby Translation

¹⁴ And afterwards they made ready for themselves and for the priests; because the priests, the sons of Aaron, [were engaged] in offering up the burnt-offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests, the sons of Aaron.

¹⁵ And the singers, the sons of Asaph, were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king's seer; and the doorkeepers were at every gate; they had not to depart from their service, for their brethren the Levites prepared for them.

¹⁶ And all the service of Jehovah was prepared the same day, to hold the passover, and to offer burnt-offerings on the altar of Jehovah according to the commandment of king Josiah.
