James 4:11; James 5:9; James 5:16

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.
9 Grudge not one against another , brethren, lest ye be condemned : behold , the judge standeth before the door.
16 Confess your faults one to another, and pray one for another, that ye may be healed . The effectual fervent prayer of a righteous man availeth much.
