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.

Numbers 5:21 In-Context

19 And the priest shall cause her to swear, and shall say unto the woman, If no man have lain with thee, and if thou have not gone aside to uncleanness, being under thy husband, be thou free from this water of bitterness that causeth the curse.

20 But if thou have gone aside, being under thy husband, and if thou be defiled, and some man have lain with thee besides thy husband:

21 then the priest shall cause the woman to swear with the oath of cursing, and the priest shall say unto the woman, Jehovah make thee a curse and an oath among thy people, when Jehovah doth make thy thigh to fall away, and thy body to swell;

22 and this water that causeth the curse shall go into thy bowels, and make thy body to swell, and thy thigh to fall away. And the woman shall say, Amen, Amen.

23 And the priest shall write these curses in a book, and he shall blot them out into the water of bitterness:
