Numbers 5:19-22

19And the priest shall charge her by an oath, and say unto the woman, If no man have lain with thee, and if thou hast not gone aside to uncleanness with another instead of thy husband, be thou free from this bitter water that causeth the curse:1

20But if thou hast gone aside to another instead of thy husband, and if thou be defiled, and some man have lain with thee beside thine husband:

21Then the priest shall charge the woman with an oath of cursing, and the priest shall say unto the woman, Yhwh make thee a curse and an oath among thy people, when Yhwh doth make thy thigh to rot, and thy belly to swell;2

22And this water that causeth the curse shall go into thy bowels, to make thy belly to swell, and thy thigh to rot: And the woman shall say, Amen, amen.
