'World' in the Bible

Because you kept my command to endure, I also will keep you from the hour of testing, which is to come on the whole world, to test those who dwell on the earth.

The seventh angel sounded, and great voices in heaven followed, saying, "The kingdom of the world has become the Kingdom of our Lord, and of his Christ. He will reign forever and ever!"

The great dragon was thrown down, the old serpent, he who is called the devil and Satan, the deceiver of the whole world. He was thrown down to the earth, and his angels were thrown down with him.

All who dwell on the earth will worship him, everyone whose name has not been written from the foundation of the world in the book of life of the Lamb who has been killed.

The beast that you saw was, and is not; and is about to come up out of the abyss and to go into destruction. Those who dwell on the earth and whose names have not been written in the book of life from the foundation of the world will marvel when they see that the beast was, and is not, and shall be present.
