Sotah is a unique ceremony. No other law includes outright divine intervention. When a man suspects his wife and warns her not to be alone with a certain man and she defies him, the man brings her to the priest. The priest then performs a special ritual that involves making the woman swear innocence, read a paragraph that is written on a tablet and then dissolved in water. A mincha offering is brought and the woman drinks from the water. If she was truthful, then the Gemara says that she becomes pregnant. If she was lying, her stomach and thighs become distended and sag. Normally, any sort of punishment, even for adultery, requires two witnesses and court adjudication. Not in this case. During the ceremony, God’s name is erased in the bitter waters something that is not done anywhere else. The tractate of Sotah dissects every single word in the twenty verses of this chapter. A few examples: In verse 11, the Torah introduces the section with “Speak to the Israelite people and say to them.” The Gemara explains that the additional “and say to them” is added to include not just married women, but women who are awaiting levirate marriage and an engaged woman. These women can be warned, although they do not drink from the Sotah water. In verse 15 the Torah explains that “the man shall bring his wife to the priest.” The Gemara explains that the ceremony can only begin if the husband himself brings the wife to the temple. No one else is allowed to bring her, not even the court. In verse 18, the priest stands the woman up and places the mincha offering in her hands. The Gemara explains that if the woman was unable to stand on her own, or she did not have hands to hold the mincha, she cannot be given the bitter waters. In verse 21, the priest reads off the curse. The curse states that her thigh will droop, and her stomach will become distended. The Gemara explains that the thigh is mentioned first followed by the stomach because this is the order of the physical contact of the body parts during intercourse. When she is punished though, in verse 27, the stomach is distended first and then the thigh droops. The Gemara explains that the actual punishments happens in the order of when the waters touch her body parts- the stomach followed by the legs. Why does God intervene in this case specifically? It cannot merely be to protect the sanctity of marriage because this ceremony is not for all sexual transgressions. The key difference here is the jealousy itself. Jealousy is a powerful emotion. Left unchecked, the husband will do horrible things to his wife and the suspect. This detailed ceremony provides many opportunities for both the husband (by calming down when seeing his wife go through this ceremony) and the wife (by admitting guilt at any stage) to tap out. That could be the ultimate goal.
