'Reason' in the Bible

and by reason thereof is bound, as for the people, so also for himself, to offer for sins.

For when by reason of the time ye ought to be teachers, ye have need again that some one teach you the rudiments of the first principles of the oracles of God; and are become such as have need of milk, and not of solid food.

But solid food is for fullgrown men, even those who by reason of use have their senses exercised to discern good and evil.
