(8) In all [cases where women exempted due to Ervah exempt their rivals as well] if there was an uncertain betrothal or divorce, the rivals perform Chalitzah but Yibum is not performed for them. What is [a case of] uncertain betrothal? [If for example] he threw the betrothal [object, such as money] and it is uncertain whether it fell nearer to him or to her - that is uncertain betrothal. A doubtful divorce is [if] he wrote [the bill of divorce] in his own handwriting but it has no witnesses' [signatures] on it; or if it has witnesses' [signatures] on it but it has no date on it; or if it has a date on it but it only has one witness's [signature] on it - those are [cases of] uncertain divorce.
(9) [If there were] three brothers married to three unrelated women, and one of them [the brothers] died, and the second brother performed Ma’amar [for the widow] and dies, they [his two widows] perform Chalitzah but Yibum is not performed for them, as it is said (Devarim 25:5), "And one them dies... her husband's brother shall go in to her," [that refers to] one who is bound to one Yavam, but not to one who is bound to two Yevamim. Rabbi Shimon says: He may perform Yibum for whichever [woman] he wants and undergo Chalitzah from the other one. [If there were] two brothers married to two sisters and one of them dies, and afterwards the wife of the second brother dies, she [the widow] is forbidden to him forever because she was forbidden to him at one point.
(10) [If] two men betrothed two women and when they entered the marriage canopy they [accidentally] switched this one's [bride] for this one's [bride] they are liable for [subsequent relations with] a married woman. [If] they were brothers [they are liable for relations] with a brother's wife. And if they were sisters [they are liable for relations] with "a woman and her sister". If they were Niddot [women who have menstruated and are thereby impure, they are liable for relations] with a Niddah. And we separate them for three months [from their husbands since] they are perhaps pregnant. And if they are minors who are unable to bear [children] we return them [to their husbands] immediately. And if they are [daughters of] priests they are disqualified from [eating] Terumah [a portion of a crop given to a Kohen which becomes holy upon separation and can only be consumed by Kohanim or their households].
