1 Kings 8:64-65

64On that same day the king consecrated the middle of the courtyard in front of the house of the LORD, and there he offered the burnt offerings, the grain offerings, and the fat of the peace offerings, since the bronze altar before the LORD was too small to contain all these offerings.

65So at that time Solomon and all Israel with him—a great assembly of people from Lebo-hamath to the Brook of Egypt—kept the feast before the LORD our God for seven days and seven more days—fourteen days in all.
