“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 curse and an oath among thy people, when the LORD doth make thy thigh to rot, and thy belly to swell;”
King James Version (KJV)
5:21 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 #Gen 46:26|, #Exo 1:5|, and other authors. To rot - Heb. 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.
