James 2:8-11

If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: but if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
