The King James Bible addresses judging others in several passages:
Matthew 7:1-5 (KJV)
1 Judge not, that ye be not judged. 2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. 3 And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye? 4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? 5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.
Luke 6:37 (KJV)
37 Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven:
Romans 2:1 (KJV)
1 Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things.
James 4:11-12 (KJV)
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. 12 There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?
John 8:7 (KJV)
7 So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
