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.The trial of jealousy. Since the crime of adultery is especially defiling and destructive of the very foundations of social order, the whole subject is dealt with at a length proportionate to its importance. The process prescribed has lately been strikingly illustrated from an Egyptian "romance," which refers to the time of Rameses the Great, and may therefore well serve to illustrate the manners and customs of the Mosaic times. This mode of trial, like several other ordinances, was adopted by Moses from existing and probably very ancient and widely spread institutions.12-15. if any man's wife go aside, and commit a trespass against him—This law was given both as a strong discouragement to conjugal infidelity on the part of a wife, and a sufficient protection of her from the consequences of a hasty and groundless suspicion on the part of the husband. His suspicions, however, were sufficient in the absence of witnesses (Le 20:10) to warrant the trial described; and the course of proceeding to be followed was for the jealous husband to bring his wife unto the priest with an offering of barley meal, because none were allowed to approach the sanctuary empty handed (Ex 23:15). On other occasions, there were mingled with the offering, oil which signified joy, and frankincense which denoted acceptance (Ps 141:2). But on the occasion referred to, both these ingredients were to be excluded, partly because it was a solemn appeal to God in distressing circumstances, and partly because it was a sin offering on the part of the wife, who came before God in the character of a real or suspected offender. The spirit of jealousy, i.e. a strong opinion or suggestion or inward motion of that kind, whether from a good or evil spirit. Thus we read of the spirit of wisdom, Isaiah 11:2, of perverseness, Isaiah 19:14, of fornication, Hosea 4:12, of fear, 2 Timothy 1:7, of slumber, Romans 11:8.

And the spirit of jealousy come upon him,.... A thought rises up in his mind, a strong suspicion works in him, which he cannot resist and throw off, but it remains with him, and makes him very uneasy, that his wife has defiled his bed, as it follows:

and he be jealous of his wife, and she be defiled; that his wife is defiled by a man; and which is the real case, as it afterwards appears, though at present he is not certain, only has a suspicion of it:

or if the spirit of jealousy come upon him, and he be jealous of his wife, and she be not defiled; it is mere jealousy and suspicion, without any foundation for it; and his wife proved a chaste and virtuous woman; yet be it which it would, he being jealous, the following law was to take place, and the following rules to be observed.

And the spirit of jealousy come upon him, and he be jealous of his wife, and she be defiled: or if the spirit of jealousy come upon him, and he be jealous of his wife, and she be not defiled:
