2 Chronicles

Wherefore all the men of Israel assembled themselves unto the king in the feast which was in the seventh month.

In the same day the Lord made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:

And all the men of Israel assembled themselves unto king Solomon at the feast in the month Ethanim, which is the seventh month.

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.

Seven days ye shall offer an offering made by fire unto the Lord: on the eighth day shall be an holy convocation unto you; and ye shall offer an offering made by fire unto the Lord: it is a solemn assembly; and ye shall do no servile work therein.
