Deuteronomy 16:13

And the feast of harvest, the firstfruits of thy labors, which thou hast sown in the field: and the feast of ingathering, which is in the end of the year, when thou hast gathered in thy labors out of the field.

And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year's end.

Speak 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.

And on the fifteenth day of the seventh month ye shall have an holy convocation; ye shall do no servile work, and ye shall keep a feast unto the LORD seven days: And ye shall offer a burnt offering, a sacrifice made by fire, of a sweet savor unto the LORD; thirteen young bullocks, two rams, and fourteen lambs of the first year; they shall be without blemish: And their meat offering shall be of flour mingled with oil, three tenth deals unto every bullock of the thirteen bullocks, two tenth deals to each ram of the two rams, And a several tenth deal to each lamb of the fourteen lambs: And one kid of the goats for a sin offering; beside the continual burnt offering, his meat offering, and his drink offering. And on the second day ye shall offer twelve young bullocks, two rams, fourteen lambs of the first year without spot: And their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner: And one kid of the goats for a sin offering; beside the continual burnt offering, and the meat offering thereof, and their drink offerings. And on the third day eleven bullocks, two rams, fourteen lambs of the first year without blemish; And their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner: And one goat for a sin offering; beside the continual burnt offering, and his meat offering, and his drink offering. And on the fourth day ten bullocks, two rams, and fourteen lambs of the first year without blemish: Their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner: And one kid of the goats for a sin offering; beside the continual burnt offering, his meat offering, and his drink offering. And on the fifth day nine bullocks, two rams, and fourteen lambs of the first year without spot: And their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner: And one goat for a sin offering; beside the continual burnt offering, and his meat offering, and his drink offering. And on the sixth day eight bullocks, two rams, and fourteen lambs of the first year without blemish: And their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner: And one goat for a sin offering; beside the continual burnt offering, his meat offering, and his drink offering. And on the seventh day seven bullocks, two rams, and fourteen lambs of the first year without blemish: And their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner: And one goat for a sin offering; beside the continual burnt offering, his meat offering, and his drink offering. On the eighth day ye shall have a solemn assembly: ye shall do no servile work therein: But ye shall offer a burnt offering, a sacrifice made by fire, of a sweet savor unto the LORD: one bullock, one ram, seven lambs of the first year without blemish: Their meat offering and their drink offerings for the bullock, for the ram, and for the lambs, shall be according to their number, after the manner: And one goat for a sin offering; beside the continual burnt offering, and his meat offering, and his drink offering. These things ye shall do unto the LORD in your set feasts, beside your vows, and your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings. And Moses told the children of Israel according to all that the LORD commanded Moses.

And Moses commanded them, saying, At the end of every seven years, in the solemnity of the year of release, in the feast of tabernacles,

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

Also 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 showed unto David, and to Solomon, and to Israel his people.
