1 Kings 8:65-66

Young's Literal Translation

⁶⁵ And Solomon maketh, at that time, the festival -- and all Israel with him, a great assembly from the entering in of Hamath unto the brook of Egypt -- before Jehovah our God, seven days and seven days; fourteen days.

⁶⁶ On the eighth day he hath sent the people away, and they bless the king, and go to their tents, rejoicing and glad of heart for all the good that Jehovah hath done to David His servant, and to Israel His people.
