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; 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.
