LXX. They also speak of the world in a threefold sense; at one time meaning God himself, whom they call a being of a certain quality, having for his peculiar manifestation universal substance, a being imperishable, and who never had any generation, being the maker of the arrangement and order that we see; and who, after certain periods of time, absorbs all substance in himself, and then re-produces it from himself.
