2 Chronicles 8:12-13

12Then Solomon offered up burnt-offerings to Jehovah on the altar of Jehovah, 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, 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.
