1 Kings 8:65

So at that time Solomon and all Israel with him—a great assembly of people from Lebo-hamath to the Brook of Egypt—kept the feast before the LORD our God for seven days and seven more days—fourteen days in all.

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.
