'Saving' in the Bible

but I say unto you, that every one that putteth away his wife, saving for the cause of fornication, maketh her an adulteress: and whosoever shall marry her when she is put away committeth adultery.

But we are not of them that shrink back unto perdition; but of them that have faith unto the saving of the soul.

By faith Noah, being warned of God concerning things not seen as yet, moved with godly fear, prepared an ark to the saving of his house; through which he condemned the world, and became heir of the righteousness which is according to faith.
