'Virtue' in the Bible

According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:

And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;

And always regard the patient forbearance of our Lord as salvation, as our dear brother Paul also has written to you in virtue of the wisdom granted to him.
