2 Chronicles 8:12-13

Then Solomon offered burnt-offerings unto Jehovah on the altar of Jehovah, which he had built before the porch, even as the duty of every day required, offering according to the commandment of Moses, on the sabbaths, and on the new moons, and on the set 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.
