If he accepts it from him, good; if not, he shall rebuke him a second and a third time. Thus he is always obliged to rebuke him until the sinner strikes him and says to him, "I will not listen." If he does not prevent everything he can possibly prevent, he is ensnared in the sin of all those he could have prevented from sinning."
