Jude 1:3-5

Beloved, while I diligently tried to write to you of the salvation we have in common, I found it necessary to write and appeal to you to contend for the faith which was once delivered to the saints. For there are some men who secretly crept in, who were marked long ago for this condemnation. They are ungodly men, who pervert the grace of our God into immorality and deny the only Lord God and our Lord Jesus Christ. Now I want to remind you, though you already know, that the Lord saved the people out of the land of Egypt and afterward destroyed those who did not believe.
