Brothers, do not slander one another. Anyone who speaks against his brother or judges him speaks against the law and judges it. And if you judge the law, you are not a practitioner of the law, but a judge of it.
KJV
Speak not evil one of another, brethren. He that speaketh evil of [his] brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.
ASV
Speak not one against another, brethren. He that speaketh against a brother, or judgeth his brother, speaketh against the law, and judgeth the law: but if thou judgest the law, thou art not a doer of the law, but a judge.
