2 Chronicles 7:7-9

7Since the bronze altar that Solomon had made could not accommodate the burnt offering, the grain offering, and the fat of the fellowship offerings, Solomon first consecrated the middle of the courtyard that was in front of the Lord’s temple and then offered the burnt offerings and the fat of the fellowship offerings there.

8So Solomon and all Israel with him — a very great assembly, from the entrance to Hamath to the Brook of Egypt — observed the festival at that time for seven days.

9On the eighth day they held a solemn assembly, for the dedication of the altar lasted seven days and the festival seven days.
