'Feast of Tabernacles' in the Bible

And it shall come to pass, that everyone that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.

And if the family of Egypt goes not up, and comes not, they will have no rain; there shall be the plague, with which the LORD will smite the nations that come not up to keep the feast of tabernacles.

This shall be the punishment of Egypt, and the punishment of all nations that come not up to keep the feast of tabernacles.
