1 Thessalonians 4:9

But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.

Brotherly love (Romans 12:10; Galatians 6:10; Hebrews 13:1; 1 Peter 1:22; 1 Peter 3:8; 2 Peter 1:7) - shown in relieving distressed brethren. A C support 'YE have.' 'Aleph (') B Delta G f g, Vulgate, read 'WE have.' We need not write, as ye yourselves are taught, and that by God, in the heart, by the Holy Spirit (John 6:45; Hebrews 8:11; 1 John 2:20; 1 John 2:27). Paul indirectly exhorts, while formally omitting exhortation. It is so obvious a duty that it will occur to yourselves. Moreover, you will be the more zealous not to fall off from the high character you already have as to it.

To love, [ eis (G1519) to (G3588)] - 'with a view to your loving one another.' Divine teachings have their confluence in love (Bengel).
