2 Chronicles 8:13-15

Authorized (King James) Version

¹³ even after a certain rate every day, offering according to the commandment of Moses, on the sabbaths, and on the new moons, and on the solemn feasts, three times in the year, even in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles.

¹⁴ And he appointed, according to the order of David his father, the courses of the priests to their service, and the Levites to their charges, to praise and minister before the priests, as the duty of every day required: the porters also by their courses at every gate: for so had David the man of God commanded. ¹⁵ And they departed not from the commandment of the king unto the priests and Levites concerning any matter, or concerning the treasures.
