Brothers and sisters, do not slander one another. Anyone who speaks against a brother or sister or judges them speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it. (NIV)
[My] brethren, do not speak evil about or accuse one another. He that maligns a brother or judges his brother is maligning and criticizing the Law and judging the Law. But if you judge the Law, you are not a practicer of the Law but a censor and judge [of it]. (AMP)
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. (KJV)
