21 (then the priest hath caused the woman to swear with an oath of execration, and the priest hath said to the woman) -- Jehovah doth give thee for an execration, and for a curse, in the midst of thy people, in Jehovah's giving thy thigh to fall, and thy belly to swell,

Numbers 5:21 Meaning and Commentary

Numbers 5:21

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.
