21 then the priest shall cause the woman to swear with the oath of cursing, and the priest shall tell the woman, "Yahweh make you a curse and an oath among your people, when Yahweh allows your thigh to fall away, and your body to swell;

The Lord make thee a curse and an oath - Let thy name and punishment be remembered and mentioned as an example and terror to all others. Like that mentioned Jeremiah 29:22, Jeremiah 29:23 : "The Lord make thee like Zedekiah, and like Ahab, whom the king of Babylon roasted in the fire, because they have committed villany in Israel, and have committed adultery with their neighbors' wives." - Ainsworth.
Then the priest shall charge the woman with an oath of cursing, and the priest shall say unto the woman, The LORD make thee a (k) curse and an oath among thy people, when the LORD doth make thy thigh to rot, and thy belly to swell;
(k) Both because she had committed so heinous a fault, and forswore herself in denying the same.
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.
The Lord make thee a curse, &c.--a usual form of imprecation (Isaiah 65:15; Jeremiah 29:22).
An oath - That is, a form of cursing, that when they would curse a person, they may wish that they may be as miserable as thou wast. Thy thigh - A modest expression, used both in scripture, as Genesis 46:26, Exodus 1:5, and other authors. To rot - Hebrews. to fall, that is, to die or waste away. To swell - Suddenly and violently till it burst, which the Jews note was frequent in this case. And it was a clear evidence of the truth of their religion.
