delirare ea, to be wholly captivated by her, so that one is no longer in his own power, can no longer restrain himself - the usual word for the intoxication of love and of wine, Pro 20:1 (Fl.).
Verse 20
The answer to the Why? in this verse is: no reasonable cause - only beastly sensuality, only flagitious blindness can mislead thee. The ב of בזרה is, as 19b and Isa 28:7, that of the object through which one is betrayed into intoxication. חק (thus, according to the Masora, four times in the O.T. for חיק) properly means an incision or deepening, as Arab. hujr (from hjr, cohibere), the front of the body, the part between the arms or the female breasts, thus the bosom, Isa 40:11 (with the swelling part of the clothing, sinus vestis, which the Arabs call jayb), and the lap; חבּק (as Pro 4:8), to embrace, corresponds here more closely with the former of these meanings; also elsewhere the wife of any one is called אשת חיקו or השׁכבת בחיקו, as she who rests on his breast. The ancients, also J. H. Michaelis, interpret Pro 5:15-20 allegorically, but without thereby removing sensual traces from the elevated N.T. consciousness of pollution, striving against all that is fleshly; for the castum cum Sapientia conjugium would still be always represented under the figure of husband and wife dwelling together. Besides, though זרה might be, as the contrast of חכמה, the personified lust of the world and of the flesh, yet 19a is certainly not the חכמה, but a woman composed of flesh and blood. Thus the poet means the married life, not in a figurative sense, but in its reality - he designedly describes it thus attractively and purely, because it bears in itself the preservative against promiscuous fleshly lust.
Verses 21-23
That the intercourse of the sexes out of the married relationship is the commencement of the ruin of a fool is now proved. 21 For the ways of every one are before the eyes of Jahve, And all his paths He marketh out. 22 His own sins lay hold of him, the evil-doer, And in the bands of his sins is he held fast. 23 He dies for the want of correction, And in the fulness of his folly he staggers to ruin.
It is unnecessary to interpret נכח as an adverbial accusative: straight before Jahve's eyes; it may be the nominative of the predicate; the ways of man (for אישׁ is here an individual, whether man or woman) are an object (properly, fixing) of the eyes
