1 Kings 8:65-66

King James Version

⁶⁵ And at that time Solomon held a feast, and all Israel with him, a great congregation, from the entering in of Hamath unto the river of Egypt, before the Lord our God, seven days and seven days, even fourteen days.

⁶⁶ On the eighth day he sent the people away: and they blessed the king, and went unto their tents joyful and glad of heart for all the goodness that the Lord had done for David his servant, and for Israel his people.
