1 Kings 8:64-65

64On that same day the king consecrated the middle of the courtyard that was in front of the house (temple) of the Lord; for he offered there the burnt offerings, the grain offerings, and the fat of the peace offerings, because the bronze altar that was before the Lord was too small to hold [all] the burnt offerings, the grain offerings and the fat of the peace offerings.

65So at that time Solomon held the feast, and all Israel with him, a great assembly, from the entrance of Hamath [on the northern border of Israel] to the Brook of Egypt [at Israel’s southern border], before the Lord our God, for seven days and seven more days [beyond the prescribed period for the Feast of Booths], fourteen days in all.
