'Feast of Tabernacles' in the Bible

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.
