'World's' in the Bible

so that that should be fulfilled which was spoken through the prophet, saying, I will open my mouth in parables; I will utter things hidden from the world's foundation.

Then shall the King say to those on his right hand, Come, blessed of my Father, inherit the kingdom prepared for you from the world's foundation:

for from the world's creation the invisible things of him are perceived, being apprehended by the mind through the things that are made, both his eternal power and divinity, so as to render them inexcusable.

But if their fall be the world's wealth, and their loss the wealth of the nations, how much rather their fulness?

For if their casting away be the world's reconciliation, what their reception but life from among the dead?

according as he has chosen us in him before the world's foundation, that we should be holy and blameless before him in love;

But whoso may have the world's substance, and see his brother having need, and shut up his bowels from him, how abides the love of God in him?
