Parallel
1 Thessalonians 4:9
Clementine Vulgate · Berean Standard Bible
De caritate autem fraternitatis non necesse habemus scribere vobis : ipsi enim vos a Deo didicistis ut diligatis invicem.
Now about brotherly love, you do not need anyone to write to you, because you yourselves have been taught by God to love one another.
