(12) How have I hated instruction.--The last stage of misery is the remorse which comes too late. (Comp. Matthew 25:30.)

Verse 12. - Self-reproach accompanies the unavailable groaning. And say, How have I hated instruction, and my heart despised reproof! i.e. how could it ever come to pass that I have acted in such a senseless and inexcusable manner, that I have hated instruction (musar, disciplina, παιδεία), the warning voice which dissuaded me from going with the harlot, and in my heart despised, i.e. rejected inwardly, whatever my outward demeanour may have been, the reproof which followed after I had been with her! Despised (naats), as in Proverbs 1:30; comp. also Proverbs 15:5, "A fool despiseth his father's instructions."

5:1-14 Solomon cautions all young men, as his children, to abstain from fleshly lusts. Some, by the adulterous woman, here understand idolatry, false doctrine, which tends to lead astray men's minds and manners; but the direct view is to warn against seventh-commandment sins. Often these have been, and still are, Satan's method of drawing men from the worship of God into false religion. Consider how fatal the consequences; how bitter the fruit! Take it any way, it wounds. It leads to the torments of hell. The direct tendency of this sin is to the destruction of body and soul. We must carefully avoid every thing which may be a step towards it. Those who would be kept from harm, must keep out of harm's way. If we thrust ourselves into temptation we mock God when we pray, Lead us not into temptation. How many mischiefs attend this sin! It blasts the reputation; it wastes time; it ruins the estate; it is destructive to health; it will fill the mind with horror. Though thou art merry now, yet sooner or later it will bring sorrow. The convinced sinner reproaches himself, and makes no excuse for his folly. By the frequent acts of sin, the habits of it become rooted and confirmed. By a miracle of mercy true repentance may prevent the dreadful consequences of such sins; but this is not often; far more die as they have lived. What can express the case of the self-ruined sinner in the eternal world, enduring the remorse of his conscience!And say, how have I hated instruction,.... To live virtuously, and avoid the adulterous woman; this he says, as wondering at his stupidity, folly, and madness, that he should hate and abhor that which was so much his interest to have observed. Gersom interprets it of the instruction of the law; but it is much better to understand it of the instruction of the Gospel; which the carnal mind of man is enmity unto, and which they are so stupid as to abhor; when it is of so much usefulness to preserve from error and heresy, superstition, will worship, and idolatry;

and my heart despised reproof; for following the whorish woman; and which was secretly despised in the heart, and heartily too, if not expressed with the mouth: it is one part of the Gospel ministry to reprove for false doctrine and false worship, though it generally falls under the contempt of the erroneous and idolatrous.
