2 Chronicles 8:12

10These were the chief officers of King Solomon, even two-hundred fifty, who ruled over the people.

11Solomon brought up Pharaoh’s daughter out of David’s city to the house that he had built for her; for he said, “My wife shall not dwell in the house of David king of Israel, because the places where the LORD’s ark has come are holy.”

12Then Solomon offered burnt offerings to the LORD on the LORD’s altar which he had built before the porch,

13even as the duty of every day required, offering according to the commandment of Moses on the Sabbaths, on the new moons, and on the set feasts, three times per year, during the feast of unleavened bread, during the feast of weeks, and during the feast of booths.

14He appointed, according to the ordinance of David his father, the divisions of the priests to their service, and the Levites to their offices, to praise and to minister before the priests, as the duty of every day required, the doorkeepers also by their divisions at every gate, for David the man of God had so commanded.
