.3 = Beloved, while I was making every effort to write you
about our common salvation, I felt the necessity to write to you appealing that
you contend earnestly for the faith which was once for all delivered to the
Jude (possibly the half-brother of Jesus)
.5 = Now I desire to remind you, though you know all
things once for all, that the Lord, after saving a people out of the land of Egypt, subsequently destroyed those who did not believe.
Watch out for the people who sneak in and try to corrupt
the valid teaching.
