KJV:
So speak ye, and so do, as they that shall be judged by the law of liberty.
NASB:
So speak and so act as those who are to be judged by the law of liberty.
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.
NASB:
Do not speak against one another, brethren. He who speaks against a brother or judges his brother, speaks against the law and judges the law; but if you judge the law, you are not a doer of the law but a judge of it.
