Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.

But I wish you to remember, once having known all these things, that the Lord, having saved the people out of the land of Egypt, destroyed them that believed riot, the second time:

Alas for them! because - in the way of Cain have they gone, and, in the error of Balaam's wage, have they run riot, and, in the gainsaying of Korah, have they perished.
