2 Chronicles 8:7-13
English Standard Version
Chapter 8
7All the people who were left of the Hittites, the Amorites, the Perizzites, the Hivites, and the Jebusites, who were not of Israel, 8from their descendants who were left after them in the land, whom the people of Israel had not destroyed — these Solomon drafted as forced labor, and so they are to this day. 9But of the people of Israel Solomon made no slaves for his work; they were soldiers, and his officers, the commanders of his chariots, and his horsemen. 10And these were the chief officers of King Solomon, 250, who exercised authority over the people.
12Then Solomon offered up burnt offerings to the Lord on the altar of the Lord that he had built before the vestibule,
13as the duty of each day required, offering according to the commandment of Moses for the Sabbaths, the new moons, and the three annual feasts — the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Booths.
