2 Chronicles 35:14-16

New Catholic Bible

¹⁴ Afterward they prepared the Passover for themselves and for the priests, since the priests, the descendants of Aaron, were kept occupied until nightfall in offering holocausts and the fatty portions. Therefore, the Levites prepared the Passover for themselves and for the priests, the descendants of Aaron. ¹⁵ The singers, the descendants of Asaph, were in their designated places in accordance with the command laid down by David, and also by Asaph, Heman, and the king’s seer, Jeduthun. The gatekeepers were stationed at each gate. They did not need to leave their stations, inasmuch as their brethren, the Levites, made the preparations for them.

¹⁶ Thus the entire service of the Lord was arranged on that day in order to celebrate the Passover and the Feast of Unleavened Bread for seven days.
