'Virtue' in the Bible

But I say to you that everyone who puts away his wife for any other cause but the loss of her virtue, makes her false to her husband; and whoever takes her as his wife after she is put away, is no true husband to her.

You, therefore, will be perfect [growing into spiritual maturity both in mind and character, actively integrating godly values into your daily life], as your heavenly Father is perfect.

And I say to you, Whoever puts away his wife for any other cause than the loss of her virtue, and takes another, is a false husband: and he who takes her as his wife when she is put away, is no true husband to her.
