2 Chronicles 7:7-9

7Furthermore Solomon consecrated the middle of the court that was in front of the house of the Lord; for there he offered burnt offerings and the fat of the peace offerings, because the bronze altar which Solomon had made was not able to receive the burnt offerings, the grain offerings, and the fat.

8At that time Solomon kept the feast seven days, and all Israel with him, a very great assembly from the entrance of Hamath to the Brook of Egypt.

9And on the eighth day they held a sacred assembly, for they observed the dedication of the altar seven days, and the feast seven days.
