Jude 1:3-4

3Loved ones, though very eager to write to you about our common salvation, I felt it necessary to write to you urging you to continue to contend for the faith that was once for all handed down to the kedoshim.

4For certain people have secretly slipped in—those who from long ago have been marked out for this judgment. They are ungodly people, who pervert the grace of our God into indecency and deny our only Master and Lord, Yeshua the Messiah.
