“For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.”
King James Version (KJV)
3:2 The same is able to bridle the whole body - That is, the whole man. And doubtless some are able to do this, and so are in this sense perfect.
Jas 3:2 For in many things we offend all. All are liable to stumble and make mistakes. These can hardly be excused in the teacher. If any man offend not in word, the same [is] a perfect man. He who controls his tongue gives proof of his ability to maintain entire self control.
