1Jn 3:11-13 (King James)

   ¹¹ For this is the message that ye heard from the beginning, that we should love one another. ¹² Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous. ¹³ Marvel not, my brethren, if the world hate you.

1Jn 3:11-13 (Vulgate)

   ¹¹ quoniam hæc est annuntiatio, quam audistis ab initio, ut diligatis alterutrum.
   ¹² Non sicut Cain, qui ex maligno erat, et occidit fratrem suum. Et propter quid occidit eum ? Quoniam opera ejus maligna erant : fratris autem ejus, justa.
   ¹³ Nolite mirari, fratres, si odit vos mundus.
