This is the law of jealousies - And this is the most singular law in the whole Pentateuch: a law that seems to have been copied by almost all the nations of the earth, whether civilized or barbarian, as we find that similar modes of trial for suspected offenses were used when complete evidence was wanting to convict; and where it was expected that the object of their worship would interfere for the sake of justice, in order that the guilty should be brought to punishment, and the innocent be cleared. For general information on this head see at the end of this chapter. (See Numbers 5:31 (note)).

This is the law of jealousies,.... Which was appointed by God to deter wives from adultery, and preserve the people of Israel, the worshippers of him, from having a spurious brood among them; and to keep husbands from being cruel to their wives they might be jealous of, and to protect virtue and innocence, and to detect lewdness committed in the most secret manner; whereby God gave proof of his omniscience, that he had knowledge of the most private acts of uncleanness, and was the avenger of all such. The reasons why such a law was not made equally in favour of women, as of men, are supposed to be these: because of the greater authority of the man over the woman, which would seem to be lessened, if such a power was granted her; because marriage was not so much hurt, or so much damage came to families by the adultery of men, as of women; because women are more apt to be suspicious than men, and in those times more prone to adultery, through their eager desire of children, that they might not lie under reproach (o):

when a wife goeth aside to another instead of her husband, and is defiled; is suspected of going aside to another man, and is supposed to be defiled by him.

(o) Vid. Salden. ut supra, (Otia, l. 1. Exercitat. 6.) sect. 19.

Numbers 5:29-31 bring the law of jealousy to a formal close, with the additional remark, that the man who adopted this course with a wife suspected of adultery was free from sin, but the woman would bear her guilt (see Leviticus 5:1), i.e., in case she were guilty, would bear the punishment threatened by God. Nothing is said about what was to be done in case the woman refused to take the oath prescribed, because that would amount to a confession of her guilt, when she would have to be put to death as an adulteress, according to the law in Leviticus 20:10; and not she alone, but the adulterer also. In the law just mentioned the man is placed on an equality with the woman with reference to the sin of adultery; and thus the apparent partiality, that a man could sue his wife for adultery, but not the wife her husband, is removed. But the law before us applied to the woman only, because the man was at liberty to marry more than one wife, or to take concubines to his own wife; so that he only violated the marriage tie, and was guilty of adultery, when he formed an illicit connection with another man's wife. In that case, the man whose marriage had been violated could proceed against his adulterous wife, and in most instances convict the adulterer also, in order that he might receive his punishment too. For a really guilty wife would not have made up her mind so easily to take the required oath of purification, as the curse of God under which she came was no easier to bear than the punishment of death. For this law prescribed no ordeal whose effects were uncertain, like the ordeals of other nations, but a judgment of God, from which the guilty could not escape, because it had been appointed by the living God.

This is the law of jealousies, when a wife goeth aside to another instead of her husband, and is defiled;

29. This is the law of jealousies-Adultery discovered and proved was punished with death. But strongly suspected cases would occur, and this law made provision for the conviction of the guilty person. It was, however, not a trial conducted according to the forms of judicial process, but an ordeal through which a suspected adulteress was made to go-the ceremony being of that terrifying nature, that, on the known principles of human nature, guilt or innocence could not fail to appear. From the earliest times, the jealousy of Eastern people has established ordeals for the detection and punishment of suspected unchastity in wives. The practice was deep-rooted as well as universal. And it has been thought, that the Israelites being strongly biassed in favor of such usages, this law of jealousies "was incorporated among the other institutions of the Mosaic economy, in order to free it from the idolatrous rites which the heathens had blended with it." Viewed in this light, its sanction by divine authority in a corrected and improved form exhibits a proof at once of the wisdom and condescension of God.

5:11-31 This law would make the women of Israel watch against giving cause for suspicion. On the other hand, it would hinder the cruel treatment such suspicions might occasion. It would also hinder the guilty from escaping, and the innocent from coming under just suspicion. When no proof could be brought, the wife was called on to make this solemn appeal to a heart-searching God. No woman, if she were guilty, could say Amen to the adjuration, and drink the water after it, unless she disbelieved the truth of God, or defied his justice. The water is called the bitter water, because it caused the curse. Thus sin is called an evil and a bitter thing. Let all that meddle with forbidden pleasures, know that they will be bitterness in the latter end. From the whole learn, 1. Secret sins are known to God, and sometimes are strangely brought to light in this life; and that there is a day coming when God will, by Christ, judge the secrets of men according to the gospel, Ro 2:16. 2 In particular, Whoremongers and adulterers God will surely judge. Though we have not now the waters of jealousy, yet we have God's word, which ought to be as great a terror. Sensual lusts will end in bitterness. 3. God will manifest the innocency of the innocent. The same providence is for good to some, and for hurt to others. And it will answer the purposes which God intends.
