An inheritance may be gotten hastily at the beginning; but the end thereof shall not be blessed.

Jamieson-Fausset-Brown Bible Commentary

21. gotten hastily-contrary to God's providence (Pr 28:20), implying its unjust or easy attainment; hence the man is punished, or spends freely what he got easily (compare Pr 20:17).

Matthew Henry's Concise Commentary

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.

Matthew Henry's Whole Bible Commentary

Verse 21

Note, 1. It is possible that an estate may be suddenly raised. There are those that will be rich, by right or wrong, who make no conscience of what they say or do if they can but get money by it, who, when it is in their power, will cheat their own father, and who sordidly spare and hoard up what they get, grudging themselves and their families food convenient and thinking all lost but what they buy land with or put out to interest. By such ways as these a man may grow rich, may grow very rich, in a little time, at his first setting out. 2. An estate that is suddenly raised is often as suddenly ruined. It was raised hastily, but, not being raised honestly, it proves soon ripe and soon rotten: The end thereof shall not be blessed of God, and, if he do not bless it, it can neither be comfortable nor of any continuance; so that he who got it at the end will be a fool. He had better have taken time and built firmly.
