הלכה אויף במדבר 5:13

The seclusion mentioned in the Torah - "And she secludes herself" - is that she secludes herself with the same man about whom her husband had told her, "Do not seclude yourself with him," in the presence of two witnesses. If she remained with him long enough to defile herself, which is the time it takes to roast an egg and swallow it, then she is forbidden to her husband until she drinks the bitter waters and the matter is examined. And when there are no Sotah waters, she becomes forbidden to her husband forever and she leaves the marriage without a kesubah.

And there are women that do not drink even though they and their husbands want [it]. And they are fifteen women and these are them: a raped woman (see note), and one waiting to perform levirate marriage, as it is written (Numbers 5:29), “underneath (tachat) her husband” — and these are not yet underneath a husband; a minor [who is] the wife of an adult, as it is written, “whereby a woman strays” — and this one is not yet a woman; an adult [who is] the wife of a minor, as it is written, “underneath her husband (literally, man)” — and this one is not yet a man; the wife of a man of unclear sex (androginos), as it is written, “her man” — and this one is not completely a man; the wife of a blind man, as it is written (Numbers 5:13), “and it is hidden from the eyes of her husband” — and this one has no eyes; a lame woman, as it is written (Numbers 5:18), “And the priest will make the woman stand” — and this one is not able to stand; one who does not have a palm of the hand, as it is written, “and he gives into her palms” — and this one does not have a palm; so [too] if her hand is crooked or paralyzed, such that she can only take it with one hand alone, she does not drink, as it is written, “into her palms”; a mute, as it is written (Numbers 5:22), “and the woman says”; one who does not hear, as it is written (Numbers 5:19) “and he says to the woman”; so [too,] [if] he be lame or stump-armed or mute or deaf, and so [if] she is blind, as it is written (Numbers 5:29), “a woman tachat her husband” (here, the word tachat is understood as “corresponding to”) — until she be complete like he, and he like her. [These] and the rest of all its details, the order of the drinking of the sotah and which angles does the water test and which angles does it not test is all well elucidated in the tractate that is built on it, and that is Tractate Sotah. (See Tur, Even HaEzer 148.)
