pro 31:1(Pro. 31:1-31)
On the title of this, the sixth part of the book, see Introduction.
prophecy--(See on Pro 30:1).
pro 31:2What, my son?--that is, What shall I say? Repetitions denote earnestness.
son of my womb--as our phrase, "my own son," a term of special affection.
son of my vows--as one dedicated to God; so the word "Lemuel" may mean.
pro 31:3Succinct but solemn warnings against vices to which kings are peculiarly tempted, as carnal pleasures and oppressive and unrighteous government are used to sustain sensual indulgence.
strength--mental and bodily resources for health and comfort.
thy ways--or course of life.
to that . . . kings--literally, "to the destroying of kings," avoid destructive pleasures (compare Pro 5:9; Pro 7:22, Pro 7:27; Hos 4:11).
pro 31:4Stimulants enfeeble reason, pervert the heart, and do not suit rulers, who need clear and steady minds, and well-governed affections (compare Pro 20:1; Pro 22:29).
pervert . . . afflicted--They give unrighteous decisions against the poor.
pro 31:6The proper use of such drinks is to restore tone to feeble bodies and depressed minds (compare Psa 104:15).
pro 31:8Open . . . cause--Plead for those who cannot plead for themselves, as the orphan, stranger, &c. (compare Psa 72:12; Isa 1:17).
appointed to destruction--who are otherwise ruined by their oppressors (compare Pro 29:14, Pro 29:16).
pro 31:10This exquisite picture of a truly lovely wife is conceived and drawn in accordance with the customs of Eastern nations, but its moral teachings suit all climes. In Hebrew the verses begin with the letters of the Hebrew alphabet in order (compare Introduction to Poetical Books).
Who . . . woman--The question implies that such are rare, though not entirely wanting (compare Pro 18:22; Pro 19:14).
virtuous--literally, "of strength," that is, moral courage (compare Pro 12:4; Rut 3:11).
her price, &c.--(compare Pro 3:15).
pro 31:11heart . . . trust in her--He relies on her prudence and skill.
no need of spoil--does not lack profit or gain, especially, that obtained by the risk of war.
pro 31:12do . . . good--contribute good to him.
pro 31:13Ancient women of rank thus wrought with their hands; and such, indeed, were the customs of Western women a few centuries since. In the East also, the fabrics were articles of merchandise.
pro 31:15She diligently attends to expending as well as gathering wealth;
pro 31:16and hence has means to purchase property.
pro 31:17To energy she adds a watchfulness in bargains, and a protracted and painful industry. The last clause may figuratively denote that her prosperity (compare Pro 24:20) is not short lived.
pro 31:19No work, however mean, if honest, is disdained.
pro 31:20Industry enables her to be charitable.
pro 31:21scarlet--or, "purple," by reason of the dyes used, the best fabrics; as a matter of taste also; the color suits cold.
pro 31:22coverings of tapestry--or, "coverlets," that is, for beds.
silk--or, "linen" (compare Exo 26:1; Exo 27:9)
and purple--that is, the most costly goods.
pro 31:23in the gates--(compare Pro 22:22). His domestic comfort promotes his advancement in public dignity.
pro 31:24fine linen--or, "linen shirts," or the material for them.
girdles--were often costly and highly valued (Sa2 18:11).
delivereth--or, "giveth as a present" or "to sell."
pro 31:25Strength and honour--Strong and beautiful is her clothing; or, figuratively, for moral character, vigorous and honorable.
shall rejoice . . . come--in confidence of certain maintenance.
pro 31:26Her conversation is wise and gentle.
pro 31:27(Compare Ti1 5:14; Tit 2:5). She adds to her example a wise management of those under her control.
pro 31:28She is honored by those who best know her.
pro 31:29The words are those of her husband, praising her.
virtuously--(Compare Pro 31:10).
pro 31:30Favour--or, "Grace" of personal manner.
beauty--of face, or form (compare Pro 11:22). True piety alone commands permanent respect and affection (Pe1 3:3).
pro 31:31The result of her labor is her best eulogy. Nothing can add to the simple beauty of this admirable portrait. On the measure of its realization in the daughters of our own day rest untold results, in the domestic, and, therefore, the civil and religious, welfare of the people.
