1 Kings 8:2And all the men of Israel assembled themselves unto king Solomon at the feast in the month Ethanim, which is the seventh month.
2 Chronicles 7:8-10Also at the same time Solomon kept the feast seven days, and all Israel with him, a very great congregation, from the entering in of Hamath unto the river of Egypt. And in the eighth day they made a solemn assembly: for they kept the dedication of the altar seven days, and the feast seven days. And on the three and twentieth day of the seventh month he sent the people away into their tents, glad and merry in heart for the goodness that the LORD had shewed unto David, and to Solomon, and to Israel his people.
Leviticus 23:34-36Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the LORD. On the first day shall be an holy convocation: ye shall do no servile work therein. 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.
