2 Chronicles 7:8-10

At that time Solomon observed the feast for seven days, and all Israel with him, a very large assembly, from the entrance of Hamath to the Brook of Egypt. On the eighth day they held a celebration, for they had observed the dedication of the altar for seven days, and the feast for seven days. And on the twenty-third day of the seventh month Solomon sent the people to their tents, rejoicing and happy in heart because of the goodness that the LORD had shown to David, to Solomon, and to His people Israel.
