James 1:19
Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath:
James 4:11
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.
