'Foundation of the World' in the Bible

For we who have believed, have entered into the rest, even as he said, "So, I sware in my wrath, that they shall not enter into my rest;" and that notwithstanding the works were done from the foundation of the world.

(for in that case he must have suffered often since the foundation of the world:) but now once for all at the consummation of the ages hath he been manifested for the abolishing sin by the sacrifice of himself.
