2 Chronicles 7:8-10

8Also at the same time Solomon kept the feast seven days, and all Israel with him, a very great congregation, from the entrance of Hamath to the river of Egypt.

9And on the eighth day they made a solemn assembly: for they kept the dedication of the altar seven days, and the feast seven days.1

10And on the three and twentieth day of the seventh month he sent the people away to their tents, glad and merry in heart for the goodness that the LORD had shown to David, and to Solomon, and to Israel his people.
