"Speak unto the children of Israel, and say, 'The fifteenth day of the same seventh month shall be the feast of tabernacles, seven days unto the LORD.

Thou shalt observe the feast of tabernacles seven days long, after that thou hast gathered in thy corn and thy wine.

And held the feast of tabernacles as it is written, and offered burnt sacrifices daily, in order: according to the custom, day by day.

Every one that remaineth then of all the people, which came against Jerusalem, shall go up yearly, to worship the King, even the LORD of Hosts, and to keep the feast of tabernacles.

If the kindred of Egypt go not up, and come not, it shall not rain upon them neither. This shall be the plague wherewith the LORD will smite all Heathen, that come not up to keep the feast of tabernacles.

Yea, this shall be the sin plague of Egypt and the sin plague of all people that go not up to keep the feast of tabernacles.
