She is defiled - Does not this refer to her having been divorced, and married in consequence to another? Though God, for the hardness of their hearts, suffered them to put away their wives, yet he considered all after-marriages in that case to be pollution and defilement; and it is on this ground that our Lord argues in the places referred to above, that whoever marries the woman that is put away is an adulterer: now this could not have been the case if God had allowed the divorce to be a legal and proper separation of the man from his wife; but in the sight of God nothing can be a legal cause of separation but adultery on either side. In such a case, according to the law of God, a man may put away his wife, and a wife may put away her husband; (see Matthew 19:9); for it appears that the wife had as much right to put away her husband as the husband had to put away his wife, see Mark 10:12.

Her former husband which sent her away may not take her again to be his wife,.... Though ever so desirous of it, and having heartily repented that he had put her away: this is the punishment of his fickleness and inconstancy, and was ordered to make men cautious how they put away their wives; since when they had so done, and they had been married to another, they could not enjoy them again even on the death of the second husband; yea, though she was only espoused to him, and he had never lain with her, as Ben Melech observes, it was forbidden the former husband to marry her; though if she had only played the whore, according to the same writer, and others (a), she might return to him:

after that she is defiled; not by whoredom, for in that case she was not forbidden, as it is interpreted, but by her being married to another man; when she was defiled, not by him, or with respect to him, nor with regard to any other man, whom she might lawfully marry after the decease of her latter husband; but with respect to her first husband, being by her divorce from him, and by her marriage to another, entirely alienated and separated from him, and so prohibited to him; and thus R. Joseph Kimchi interprets this defilement of prohibition, things prohibited being reckoned unclean, or not lawful to be used:

for that is abomination before the Lord; for a man to take his wife again, after she had been divorced by him, and married to another man; and yet, such is the grace and goodness of God to his backsliding people, that he receives them when they return unto him their first husband, and forsake other lovers, Jeremiah 3:1,

and thou shalt not cause the land to sin which the Lord thy God giveth thee for an inheritance; since if this was allowed, that men might put away their wives, and take them again at pleasure, and change them as often as they thought fit, no order could be observed, and the utmost confusion in families introduced, and lewdness encouraged, and which would subject the land and the inhabitants of it to many evils and calamities, as the just punishment thereof.

(a) Maimon. & Bartenora in Misn. Sotah, c. 2. sect. 6.

Her former husband, which sent her away, may not take her again to be his wife, after that she is {b} defiled; for that is abomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee for an inheritance.

(b) Seeing that by divorcing her he judged her to be unclean and defiled.

24:4 May not - This is the punishment of his levity and injustice in putting her away without sufficient cause, which by this offer he now acknowledgeth. Defiled - Not absolutely, as if her second marriage were a sin, but with respect to her first husband, to whom she is as a defiled or unclean woman, that is, forbidden things; forbidden are accounted and called unclean, Jud 13:7, because they may no more be touched or used than an unclean thing. Thou shalt not cause the land to sin - Thou shalt not suffer such lightness to be practised, lest the people be polluted, and the land defiled and accursed by that means.

24:1-4 Where the providence of God, or his own wrong choice in marriage, has allotted to a Christian a trial instead of a help meet; he will from his heart prefer bearing the cross, to such relief as tends to sin, confusion, and misery. Divine grace will sanctify this cross, support under it, and teach so to behave, as will gradually render it more tolerable.
