NET

3 Dear friends, although I have been eager to write to you about our common salvation, I now feel compelled instead to write to encourage you to contend earnestly for the faith that was once for all entrusted to the saints.

Darby

3 Beloved, using all diligence to write to you of our common salvation, I have been obliged to write to you exhorting [you] to contend earnestly for the faith once delivered to the saints.

KJV

3 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.
