“This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;”
King James Version (KJV)
Tit 1:13 This witness is true. Paul's observations confirmed it. So do many ancient writers. "Cretize" (Cretanize) became a slang phrase for lying. Wherefore rebuke them sharply. Their bad conduct must be sharply rebuked until the gospel so transforms them that they will become "sound in the faith".
