'Worship' in the Bible

And the Lord shall be king over all the earth; in that day the Lord shall be the only one [worshiped], and His name the only one.

Then everyone who is left of all the nations that went against Jerusalem will go up from year to year to worship the King, the Lord of hosts, and celebrate the Feast of Booths (Tabernacles).

And it will be that whichever of the families of the earth does not go up to Jerusalem to worship the King, the Lord of hosts, there will be no rain on them.
