Commentary on Proverbs 20:21

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Proverbs 20:21: 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...
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Proverbs 20:21: An inheritance may be gotten hastily at the beginning,.... Of a man's setting out in the world in trade and business; and which sometimes is got lawfully, and this must be excepted from this proverb; but generally what is got hastily and in a short time is got unlawfully, and so does not prosper.
• Jamieson-Fausset-Brown (Reformed), Commentary Critical and Explanatory on the Whole Bible on Proverbs 20:21: gotten hastily--contrary to God's providence (Pro 28:20), implying its unjust or easy attainment; hence the man is punished, or spends freely what he got easily (compare Pro 20:17).
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Proverbs 20:21: Pro 20:21 21 An inheritance which in the beginning is obtained in haste, Its end will not be blessed. The partic. מבחל may, after Zec 11:8, cf. Syr. bhlaa', nauseans, mean “detested,” but that affords here no sense; rather it might be interpreted after the Arab. bajila, to be avaricious, “gotten by avarice, niggardliness,” with which, however, neither נחלה, inheritance, nor, since avarice is a chronic disease, בּראשׁונה agrees.
