Here is, 1. An undutiful child become very wicked by degrees. He began with despising his father and mother, slighting their instructions, disobeying their commands, and raging at their rebukes, but at length he arrives at such a pitch of impudence and impiety as to curse them, to give them scurrilous and opprobrious language, and to wish mischief to those that were instruments of his being and have taken so much care and pains about him, and this in defiance of God and his law, which had made this a capital crime (Exo 21:17, Mat 15:4), and in violation of all the bonds of duty, natural affection, and gratitude. 2. An undutiful child become very miserable at last: His lamp shall be put out in obscure darkness; all his honour shall be laid in the dust, and he shall for ever lose his reputation. Let him never expect any peace or comfort in his own mind, no, nor to prosper in this world. His days shall be shortened, and the lamp of his life extinguished, according to the reverse of the promise of the fifth commandment. His family shall be cut off and his posterity be a curse to him. And it will be his eternal ruin; the lamp of his happiness shall be put out in the blackness of darkness (so the word is), even that which is for ever, Jde 1:13, Mat 22:13.

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 Pro 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, Pro 20:27; shall be removed; or he "shall die", not only a corporeal but an eternal death; see Exo 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.
