'Of the World' in the Bible

For we who have believed are to enter into rest, as he said: So I swore in my anger, they shall not enter into my rest; namely, that rest from his works which had been finished from the foundation of the world.

for then, he must have suffered often since the foundation of the world. But now once in the end of the ages, he has appeared in order to put away sin by the sacrifice of himself.
