Prov 23:13

“As small children who are negligent in learning become more attentive and obedient after being punished by their teacher or tutor, and as they do not listen before the lash, but, after feeling the pain of a beating, hear and respond as though their ears were just recently opened, improving also in memory, so likewise with those who neglect divine doctrine and spurn the commandments. For, after they experience God's correction and discipline, then the commandments of God which had always been known to them and always neglected are most readily received as though by ears freshly cleansed.”

“When someone presumes to commit a sin against God, he ought to suffer a monastic penance. This should be done in a kind and devout spirit, so that through rebuke he may be corrected in this life in such a way that he may not perish in the future. For every sin which is not corrected in this world will be punished in the future life. Sacred Scripture speaks thus about the son and the servant: "Strike him with the rod," it says, "and you will save him from the nether world."”

“13 Withhold not correction from the child; For thou will beat him with the rod, and he will not die. 14 Thou beatest him with the rod, And with it deliverest his soul from hell. The exhortation, 13a, presupposes that education by word and deed is a duty devolving on the father and the teacher with regard to the child. In 13b, כּי is in any case the relative conjunction. The conclusion does not mean: so will he not fall under death (destruction), as Luther also would have it, after Deu 19:21, for this thought certainly follows Pro 23:14; nor after Pro 19:18 : so may the stroke not be one whereof he dies, for then the author ought to have written אל־תּמיתנּוּ; but: he will not die of it, i.e., only strike if he has deserved it, thou needest not fear; the bitter medicine will be beneficial to him, not deadly. The אתּה standing before the double clause, Pro 23:14, means that he who administers corporal chastisement to the child, saves him spiritually; for שׁאול does not refer to death in general, but to death falling upon a man before his time, and in his sins, vid., Pro 15:24, cf. Pro 8:26.”
