19 The priest will then put the woman under oath and say to her, 'If no other man has had sex with you, and you have not gone astray and defiled yourself while under your husband's authority, may you be immune from the effects of this bitter water that brings on the curse. 20 But if you have gone astray by being unfaithful to your husband, and have defiled yourself by having sex with another man-' 21 "At this point the priest must put the woman under oath by saying, 'May the people know that the Lord 's curse is upon you when he makes you infertile, causing your womb to shrivel and your abdomen to swell. 22 Now may this water that brings the curse enter your body and cause your abdomen to swell and your womb to shrivel. ' And the woman will be required to say, 'Yes, let it be so.'
Matthew Henry's Commentary on Numbers 5:19-22
Commentary on Numbers 5:11-31
(Read Numbers 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, Romans 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.
