2 Chronicles 7:6-10

The priests stood at their posts, and the Levites also, with the musical instruments for the Lord, which King David had made for giving praise to the Lord—“for His faithfulness is everlasting”—whenever David gave praise through their ministry; the priests on the other side blew trumpets and all Israel was standing.

Then Solomon consecrated the middle of the courtyard that was before the house of the Lord, for he offered the burnt offerings and the fat of the peace offerings there, because the bronze altar which Solomon had made was not able to contain the burnt offering, the grain offering, and the fat. The Feast of Dedication

So Solomon held the feast at that time for seven days, and all Israel with him, a very great assembly that came from the entrance of Hamath to the brook of Egypt.

And on the eighth day they held a solemn assembly, because they held the dedication of the altar for seven days, and the feast for seven days.

Then on the twenty-third day of the seventh month he 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. God’s Promise and Warning
