Verse 21. - Then the priest shall say unto the woman. These words are parenthetical, just as in Matthew 9:6. The latter part of the oath is called "an oath of cursing," because it contained the imprecations on the guilty. To rot. Hebrew, "to fall." Τὸν μηρόν σου διαπεπτωκότα,, Septuagint. To swell. The Hebrew zabeh is not of quite certain meaning, but probably this.

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.Then the priest shall charge the woman with an oath of cursing,.... An oath which has a curse annexed to it, if taken falsely, which was to be pronounced upon the woman if guilty:

and the priest shall say unto the woman; pronouncing the imprecation or curse upon her, she having taken the oath, should she be guilty of the crime suspected of, and she had swore concerning:

the Lord make thee a curse, and an oath among the people; accursed according to the oath taken; or let this be the form of an oath and imprecation used by the people, saying, if I have done so and so, let me be accursed as such a woman, or let not that happen to me, as did to such a woman, so Jarchi:

when the Lord doth make thy thigh to rot, and thy belly to swell; upon drinking the bitter waters; but though these things followed upon that, yet not as the natural cause of them, for they are ascribed to the Lord, and to a supernatural and miraculous power of his, which went along with the drinking of them.
