“But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.”
King James Version (KJV)
4:9 We need not write - Largely. For ye are taught of God - By his Spirit.
1Th 4:9 But as touching brotherly love. This subject springs out of 1Th 4:6. For ye yourselves are taught of God to love one another. The whole gospel teaches you to love one another. When you are born of God, you are his children and all brethren. As Christ loved the brethren, so must you if you follow him.
