A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown  at sacred-texts.com
pro 11:1(Pro. 11:1-31)
(Compare Margin). The Hebrews used stones for weights.
just--complete in measure.
pro 11:2Self-conceit is unteachable; the humble grow wise (compare Pro 16:18; Pro 18:12).
pro 11:3guide--to lead, as a shepherd (Pro 6:7; Psa 78:52).
pro 11:4(Compare Pro 10:2).
wrath--that is, of God.
pro 11:5direct--or, "make plain"; wicked ways are not plain (Pro 13:17).
pro 11:6deliver them--that is, from evil, which the wicked suffer by their own doings (Pro 5:22; Psa 9:16).
pro 11:7expectation . . . perish--for death cuts short all his plans (Luk 16:25).
hope of unjust--better, "hope of wealth," or "power" (compare Isa 40:29, Hebrew). This gives an advance on the sentiment of the first clause. Even hopes of gain die with him.
pro 11:8Perhaps the trouble prepared by the wicked, and which he inherits (compare Pro 11:6).
pro 11:9(Compare Psa 35:16; Dan 11:32). The just is saved by superior discernment.
pro 11:10The last may be a reason for the first. Together, they set forth the relative moral worth of good and bad men.
pro 11:11By the blessing--implying active benevolence.
pro 11:12despiseth--or, "reviles," a course contrasted with the prudent silence of the wise.
holdeth his peace--as if neither hearing nor telling.
pro 11:13tale-bearer--(Compare Margin), one trading as a peddler in scandal, whose propensity to talk leads him to betray confidence.
pro 11:14counsel--the art of governing (Pro 1:5).
counsellors--literally, "one giving counsel"; the participle used as a collective.
pro 11:15(Compare Pro 6:1).
suretiship--(Compare Margin), the actors put for the action, which may be lawfully hated.
pro 11:16retaineth--or literally, "lay hold of as a support." Honor is to a feeble woman thus as valuable as riches to men.
pro 11:17merciful--kind to others; opposed to cruel. Such benefit themselves by doing good to others (compare Pro 24:5), while the cruel injure themselves as well as others.
flesh--that is, his body, by penuriousness (Col 2:23).
pro 11:18a deceitful work--or, "wages," which fail to satisfy, or flee away (Pro 10:2; Pro 23:5).
sure reward--or, "gain," as from trading (Hos 10:12; Gal 6:8-9).
pro 11:19Inference from Pro 11:18 (compare Pro 11:5-6; Pro 10:16).
pro 11:20(Compare Pro 11:5).
froward--as in Pro 2:15, opposed to the simplicity and purity of the upright.
in their way--or, "conduct."
pro 11:21The combined power of the wicked cannot free them from just punishment, while the unaided children of the righteous find deliverance by reason of their pious relationship (Psa 37:25-26).
pro 11:22Jewels were often suspended from the nose (Gen 24:47; Isa 3:21). Thus adorned, a hog disgusts less than a fair and indiscreet woman.
pro 11:23(Compare Pro 10:28).
wrath--is that of God.
pro 11:24The scope of the whole is a comment on Pro 11:23. Thus liberality, by God's blessing, secures increase, while penuriousness, instead of expected gain, procures poverty.
pro 11:25liberal soul--(Compare Margin).
made fat--prospers (Pro 28:25; Deu 32:15; Luk 6:38).
watereth . . . watered--a common figure for blessing.
pro 11:26Another example of the truth of Pro 11:23; the miser loses reputation, though he saves corn.
selleth it--that is, at a fair price.
pro 11:27good [and] mischief--that is, of others.
procureth . . . seeketh--implying success.
pro 11:28(Compare Pro 10:15; Psa 49:6; Ti1 6:17).
righteous . . . branch-- (Psa 1:3; Jer 17:8).
pro 11:29troubleth--as Pro 15:27 explains, by greediness for gain (compare Pro 11:17).
inherit . . . wind--Even successful, his gains are of no real value. So the fool, thus acting, either comes to poverty, or heaps up for others.
pro 11:30a tree of life--Blessings to others proceed from the works of the righteous (Pro 3:18).
winneth souls--(Compare Margin) to do them good as opposed to Pro 6:25; Eze 13:18 (compare Luk 5:10).
pro 11:31Behold--Thus calling attention to the illustrations (compare Pro 11:23), the sentiment of which is confirmed even in time, not excluding future rewards and punishments.
