pro 19:1(Pro. 19:1-29)
(Compare Pro 28:6). "Rich" for fool here. Integrity is better than riches (Pro 15:16-17; Pro 16:8).
pro 19:2The last illustrates the first clause. Rashness, the result of ignorance, brings trouble.
pro 19:3perverteth . . . way--turns him back from right (Pro 13:6; Jam 1:13); and he blames God for his failures.
pro 19:4(Compare Pro 14:20). Such facts are often adduced with implied disapprobation.
pro 19:5Compare Pro 19:9, where perish explains not escape here (compare Psa 88:9-10).
pro 19:8(Compare Margin; Pro 15:32).
loveth . . . soul--or, "himself," which he evinces by regarding his best interests.
pro 19:10(Compare Pro 17:7). The fool is incapable of properly using pleasure as knowledge, yet for him to have it is less incongruous than the undue elevation of servants. Let each abide in his calling (Co1 7:20).
pro 19:11(Compare Pro 14:29; Pro 16:32). This inculcation of a forgiving spirit shows that true religion is always the same (Mat 5:22-24).
pro 19:12(Compare Pro 16:14-15; Pro 20:2). A motive to submission to lawful authority.
pro 19:13calamity--literally, "calamities," varied and many.
continual dropping--a perpetual annoyance, wearing out patience.
pro 19:14A contrast of men's gifts and God's, who, though author of both blessings, confers the latter by His more special providence.
and--or, "but," implying that the evils of Pro 19:13 are only avoided by His care.
pro 19:15a deep sleep--a state of utter indifference.
idle soul--or, "person" (compare Pro 10:4; Pro 12:24).
pro 19:16(Compare Pro 10:17; Pro 13:13).
despiseth . . . ways--opposed to keeping or observing, neglects (Pro 16:17) (as unworthy of regard) his moral conduct.
pro 19:17(Compare Pro 14:21; Psa 37:26).
hath pity--shown by acts (compare Margin).
pro 19:18(Compare Pro 13:24; Pro 23:13).
let not . . . spare--literally, "do not lift up thy soul" (Psa 24:4; Psa 25:1), that is, do not desire to his death; a caution to passionate parents against angry chastisement.
pro 19:19Repeated efforts of kindness are lost on ill-natured persons.
pro 19:20(Compare Pro 13:18-20).
latter end-- (Pro 5:11). In youth prepare for age.
pro 19:21(Compare Pro 16:1, Pro 16:9; Psa 33:10-11). The failure of man's devices is implied.
pro 19:22desire--that is, to do good, indicates a kind disposition (Pro 11:23); and the poor thus affected are better than liars, who say and do not.
pro 19:23The fear . . . life--(Compare Pro 3:2).
abide--or, "remain contented" (Ti1 4:8).
not visited with evil-- (Pro 10:3; Psa 37:25), as a judgment, in which sense visit is often used (Psa 89:32; Jer 6:15).
pro 19:24bosom--literally, a wide dish in which the hand was plunged in eating (Mat 26:23). Compare Pro 26:15, the sentiment expressed with equal irony and less exaggeration.
pro 19:25Such is the benefit of reproof; even the simple profit, much more the wise.
pro 19:26Unfilial conduct often condemned (Pro 17:21-25; Pro 20:20; Deu 21:18, Deu 21:21).
pro 19:27Avoid whatever leads from truth.
pro 19:28ungodly witness--(Compare Margin), one false by bad principles (compare Pro 6:12).
scorneth judgment--sets at naught the dictates of justice.
devoureth--literally, "swalloweth," as something delightful.
pro 19:29Their punishment is sure, fixed, and ready (compare Pro 3:34; Pro 10:13).
