Verse 18. - Uncover the woman's head. In token that she had forfeited her glory by breaking, or seeming to have broken, her allegiance to her husband (1 Corinthians 11:5-10); perhaps also with some reference to the truth that "all things are naked and open to the eyes of him" with whom she had to do (Hebrews 4:13). Put the offering of memorial in her hands. That she herself might present, as it were, the fruits of her life before God, and challenge investigation of them. Bitter water. It was not literally bitter, but it was so fraught with conviction and judgment as to bring bitter suffering on the guilty.

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.And the priest shall set the woman before the Lord,.... In the east of the tabernacle, with her face to the west, where was the holy of holies, so Ben Gersom; but not immediately for they had her from place to place, as Jarchi says, till she was weary, and her mind disturbed, that she might confess; and if she said, I am defiled, she rent the writing of her dowry, and went out; but if she said, I am pure, they brought her to the eastern gate, the gate of Nicanor, for there they made women suspected of adultery to drink the waters (t):

and uncover the woman's head; as a token of her immodesty and non-subjection to her husband, and that she might be seen by all, to cause shame in her: according to the Misnah (u), the priest took off her clothes, and loosed her hair--if she was clothed with white garments, he clothed her with black; if she had on her ornaments of gold, chains, earrings, or rings, he took them away from her, that she might be unseemly, and whoever would might come and look at her:

and put the offering of memorial into her hands, which is the jealousy offering; to weary her, as Jarchi says, that if perhaps her mind was disturbed she would confess; and so in the Misnah (w) it is said, that her husband put this offering into her hands to weary her; but the true reason here seems to be, that it might appear to be her own offering:

and the priest shall have in his hand the bitter water that causeth the curse; not that the water was bitter of itself, for it was the water out of the laver, and had nothing in it but the dust of the floor of the tabernacle; though some think some bitter thing was put into it, so Ben Gersom, as wormwood; but it is so called from the effects of it on those that were guilty; it produced sad effects in them, bitter and distressing, and made them appear to be accursed ones, for it was not bitter till it entered, Numbers 5:24; whereas it was not so to the innocent, nor attended with any such consequence to them; so that there was nothing in the water itself, but its efficacy was divine and supernatural.
