(20) His lamp shall be put out in obscure darkness.--See above, on Proverbs 13:9.

Verse 20. - This is an enforcement of the fifth commandment, by denouncing the punishment which the moral government of God shall exact from the unnatural child. The legal penalty may be seen (Exodus 21:17; Leviticus 20:9); but this was probably seldom or never carried into execution (comp. Matthew 15:4; Mark 7:10). His lamp shall be put out in obscure (the blackest) darkness (comp. Proverbs 13:9). The expression is peculiar; it is literally, according to the Khetib, In the apple of the eye of darkness, as in Proverbs 7:9; i.e. in the very centre of darkness; he will find himself surrounded on all sides by midnight darkness, without escape, with no hope of Divine protection. "Lamp" is a metaphor applied to the bodily and the spiritual life, to happiness and prosperity, to a man's fame and reputation, to a man's posterity; and all these senses may be involved in the denunciation of the disobedient and stubborn child. He shall suffer in body and soul, in character, in fortune, in his children. His fate is the exact counterpart of the blessing promised in the Law. Septuagint, "The lamp of him that revileth father and mother shall be extinguished, and the pupils of his eyes shall behold darkness." Talmud, "Whosoever abandons his parents means his body to become the prey of scorpions." Cato, 'Dist.,' 3:23 -

"Dilige non aegra caros pietate parentes;
Nec matrem offendas, dum vis bonus esse parenti." One of the evil generations denounced by Agur (Proverbs 30:11) is that which curseth parents.

20:7. A good man is not liable to uneasiness in contriving what he shall do, or in reflecting on what he has done, as those who walk in deceit. And his family fare better for his sake. 8. If great men are good men, they may do much good, and prevent very much evil. 9. Some can say, Through grace, we are cleaner than we have been; but it was the work of the Holy Spirit. 10. See the various deceits men use, of which the love of money is the root. The Lord will not bless what is thus gotten. 11. Parents should observe their children, that they may manage them accordingly. 12. All our powers and faculties are from God, and are to be employed for him. 13. Those that indulge themselves, may expect to want necessaries, which should have been gotten by honest labour. 14. Men use arts to get a good bargain, and to buy cheap; whereas a man ought to be ashamed of a fraud and a lie. 15. He that prefers true knowledge to riches, follows the ways of religion and happiness. If we really believed this truth, the word of God would be valued as it deserves, and the world would lose its tempting influence. 16. Those ruin themselves who entangle themselves in rash suretiship. Also those who are in league with abandoned women. Place no confidence in either. 17. Wealth gotten by fraud may be sweet, for the carnal mind takes pleasure in the success of wicked devices; but it will be bitter in the reflection. 18. Especially we need advice in spiritual warfare. The word and Spirit of God are the best counsellors in every point. 19. Those dearly buy their own praise, who put confidence in a man because he speaks fairly. 20. An undutiful child will become very miserable. Never let him expect any peace or comfort. 21. An estate suddenly raised, is often as suddenly ruined. 22. Wait on the Lord, attend his pleasure, and he will protect thee.Whoso curseth his father or his mother,.... This is dreadful indeed! a person must be got to a great pitch of wickedness to do this; to curse his parents, one or other of them, that have been the instruments of his being, and by whom he has been brought up and put out into the world; to slight them, despise them, and mock at them, is highly base and criminal, but to curse them is shocking! what can such expect but the curse of God upon them?

his lamp shall be put out in obscure darkness; he shall be deprived of his natural sight; see Proverbs 30:17; or the very light of nature shall be extinct in him; and indeed such an one acts as if not guided by it, nor under its influence; or whatsoever favour from the Lord he has enjoyed, it shall be taken from him; his lamp or candle of outward felicity shall be quenched, and burn no longer; see Job 18:5; or his soul, the candle of the Lord, in him, Proverbs 20:27; shall be removed; or he "shall die", not only a corporeal but an eternal death; see Exodus 21:17; "blackness of darkness" (h) as the words may be rendered, are reserved for him in the world to come, and which will be his portion, Jde 1:13.
