Titus 1:13-15 King James Version (KJV)
13 This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;
14 Not giving heed to Jewish fables, and commandments of men, that turn from the truth.
15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
