Tit 1:10 For there are many unruly and vain talkers and deceivers, specially they of the circumcision:
Tit 1:11 Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake.
Tit 1:12 One of themselves, even a prophet of their own, said, The Cretians are alway liars, evil beasts, slow bellies.
Tit 1:13 This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;
Pro 9:8 Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee.
Pro 27:5 Open rebuke is better than secret love.
