Matthew 7:3 (KJV) – and why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye?
II Corinthians 13:5 (KJV) – examine yourselves, whether ye be in the faith: prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
