2,005. If the Suspected Woman is Innocent/Guilty

Hilchos Sotah 3:16

If the accused woman is innocent, she leaves and is permitted to her husband. If she did in fact commit adultery, then her face will turn yellow, her eyes will bulge and her veins will show. Everyone will shout that she should be taken outside, out of concern that she might have a menstrual emission in the Temple, which would render the women’s courtyard ritually unclean. She’s removed from the women's courtyard. Her belly swells first, then her thigh (a euphemism) ruptures and she dies.

Hilchos Sotah 3:17

When a guilty woman dies, the adulterer who necessitated that she drink also dies, wherever he may be. The same miraculous swelling of the belly and rupturing of the “thigh” also happens to him. All of this, however, is only the case so long as the woman’s husband never engaged in prohibited sexual relations his entire adult life. If a man ever engaged in prohibited relations, the bitter waters won’t test his wife, as we have discussed.
