2 Chronicles 8:13-15

Darby Translation

¹³ even as the duty of every day required, offering according to the commandment of Moses, on the sabbaths, and on the new moons, and at the set feasts, three times in the year,—at the feast of unleavened bread, and at the feast of weeks, and at the feast of tabernacles.

¹⁴ And he appointed, according to the ordinance of David his father, the divisions of the priests for their service, and the Levites for their charges, to praise and serve before the priests, as the duty of every day required; and the doorkeepers by their divisions at every gate: for such was the commandment of David the man of God;

¹⁵ and they did not depart from the commandment of the king to the priests and the Levites concerning any matter, nor concerning the treasures.
