'World' in the Bible

Now it came to pass in those days, there went out a decree from Caesar Augustus, that all the world should be enrolled.

And he led him up, and showed him all the kingdoms of the world in a moment of time.

For what is a man profited, if he gain the whole world, and lose or forfeit his own self?

that the blood of all the prophets, which was shed from the foundation of the world, may be required of this generation;

For all these things do the nations of the world seek after: but your Father knoweth that ye have need of these things.

And his lord commended the unrighteous steward because he had done wisely: for the sons of this world are for their own generation wiser than the sons of the light.

who shall not receive manifold more in this time, and in the world to come eternal life.

And Jesus said unto them, The sons of this world marry, and are given in marriage:

but they that are accounted worthy to attain to that world, and the resurrection from the dead, neither marry, nor are given in marriage:

men fainting for fear, and for expectation of the things which are coming on the world: for the powers of the heavens shall be shaken.
