2 Chronicles 7:7-9

71Then Solomon consecrated the middle of the courtyard that was before the house of the Lord, for he offered the burnt offerings and the fat of the peace offerings there, because the bronze altar which Solomon had made was not able to contain the burnt offering, the grain offering, and the fat.

8So 2Solomon held the feast at that time for seven days, and all Israel with him, a very great assembly that came from the entrance of Hamath to the 3brook of Egypt. 9And on the eighth day they held 4a solemn assembly, because they held the dedication of the altar for seven days, and the feast for seven days.
