2 Chronicles 7:7-9

7And Solomon hallowed the middle of the court that was before the house of Jehovah; for there he offered the burnt-offerings, and the fat of the peace-offerings, because the brazen altar which Solomon had made was not able to receive the burnt-offerings and the oblations and the fat.

8And at that time Solomon held the feast seven days, and all Israel with him, a very great congregation, from the entrance of Hamath unto the torrent of Egypt.

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