1 Kings 8:64-65

64On the same day, the king consecrated the middle of the courtyard that was in front of the Lord’s temple because that was where he offered the burnt offering, the grain offering, and the fat of the fellowship offerings, since the bronze altar before the Lord was too small to accommodate the burnt offerings, the grain offerings, and the fat of the fellowship offerings.

65Solomon and all Israel with him — a great assembly, from the entrance of Hamath to the Brook of Egypt  — observed the festival at that time in the presence of the Lord our God, seven days, and seven more days — fourteen days.
