I will not punish your daughters when they commit whoredom, nor your spouses when they commit adultery. The spiritual adultery of parents and husbands would be punished by the carnal adultery of daughters and wives; sin would thus be punished by sin.
Their own dishonor and disgrace, through the unfaithfulness of persons so near to them, would impress them with a sense of the dishonor done to God, the spiritual Husband of his people; their feeling of pain and shame in consequence would convey to them a clearer notion of the abhorrence which their offences had occasioned to God.
But their punishment would become more severe, and their pain intensified by the Divine refusal to avenge them by punishing the lewdness that caused such dishonor. While punishment would prevent the sin and consequent reproach, impunity, or the postponement of punishment, would leave the offenders to go on in their course of sin and shame.
Aben Ezra comments on this fourteenth verse as follows: "The sense is—It is not to be wondered at if the daughters commit whoredom; for they themselves, when they go up to the tops of the mountains to burn in-cerise, eat and drink with harlots and commit whoredom—all of them.
And, behold, the sense is, not that he shall not punish them at all, but he speaks in regard to, i.e. in comparison with, the fathers; for they teach them to commit whoredom doing according to their works.
Perhaps the daughters are still little, therefore I shall not punish." Rashi thinks that this threatening refers to the disuse of the bitter waters of jealousy, so that suspected guilt could not be detected.
But there is nothing to intimate such a reference; nor would it be in keeping with the scope of the passage. Again, some, as in the margin of the Authorized Version, read the words, not indicatively, but interrogatively—"Shall I not punish," etc.?
This would require such a meaning to be read into the passage as the following: "Assuredly I shall punish them; and not the daughters and daughters-in-law only, but the parents and husbands still more severely, because of their greater criminality."
Equally unsatisfactory is the explanation of Theodoret, who, taking פָקַד in a good sense, which it has with the accusative, understands it of God's refusing any protection or preservation of their daughters and spouses from outrage at the hands of a hostile soldiery, so that such sins as they themselves had been guilty in private, would be committed with the females of their family in public.
For they themselves are separated with whores, and they sacrifice with harlots. The change of person appears to imply that God turns away with inexpressible disgust from such vileness, and, turning aside to a third party, explains the grounds of his procedure.
The Qedesheth were females who devoted themselves to licentiousness in the service of Ashtaroth, the Sidonian Venus. Persons of this description were attached to idol temples and idolatrous worship in heathen lands in ancient times, as in India at the present time.
The 'Speaker's Commentary' calls them "devotee-harlots," and cites an allusion to the custom from the Moabite Stone, as follows: "I did not kill the women and maidens, for I devoted them to Ashtar-kemosh."
After stating the humiliating fact that fathers and husbands in Israel, instead of uniting with their wives in the worship of Jehovah, separated themselves, going aside with these female idolaters for the purpose of lewdness, and shared in their sacrificial feasts, the prophet, or rather God by the prophet, impatient of the recital of such shameless licentiousness, and indignant at such presumptuous sinning, closes abruptly with the declaration of the recklessness, and denunciation of the ruin of all such offenders, in the words—the people that doth not understand shall fall; margin, be punished; rather, dashed to the ground, or plunge into ruin (nilbat).
Both Aben Ezra and Kimchi give from the Arabic, as an alternative sense of silbat, to fall into error.
