2 Chronicles 7:8-10

So Solomon observed the feast at that time for seven days, and all Israel with him, a very great assembly who came from the entrance of Hamath to the brook of Egypt. On the eighth day they held a solemn assembly, for the dedication of the altar they observed seven days and the feast seven days. Then on the twenty-third day of the seventh month he sent the people to their tents, rejoicing and happy of heart because of the goodness that the LORD had shown to David and to Solomon and to His people Israel.
