2 Chronicles 7:7-9

7Moreover, Solomon consecrated the middle of the courtyard that was before the House of Adonai, because there he offered the burnt offerings and the fat of the peace offerings, since the bronze altar which Solomon had made was not able to contain the burnt offering, the grain offering and the fat.

8At that time, Solomon observed the feast for seven days and all Israel with him—a very great assembly from Lebo-hamath to the Brook of Egypt.

9On the eighth day they held a solemn assembly, for they had celebrated the dedication of the altar for seven days and the feast for seven days.
