(11) [If] four brothers marry four women and [all] die, the eldest [among other surviving brothers] he has the right to perform Yibum for all them [the widows] if he so wishes. If one was married to two wives and died, relations [for Yibum] or Chalitzah with one of them exempts her rival. [If] one is eligible and one is ineligible, [then] if [he chooses] to undergo Chalitzah he undergoes Chalitzah from the ineligible woman; and if [he chooses] to perform Yibum he performs Yibum with the eligible woman.
(12) [If] one re-marries his divorced wife, or [if] one marries his one Chalutzah [after performing Chalitzah], or [if] one marries the relative of his Chalutzah, he must divorce the woman, and any child [resulting from the union] is a Mamzer [the offspring of a severely prohibited union between a Jewish man and woman], these are the words of Rabbi Akiva; but the Sages say the child is not a Mamzer. And they agree that [if] one marries the relative of his divorced wife, the child is a Mamzer.
(13) Who is a Mamzer? [Relations with] any close relative subject to "He shall not enter" (Devarim 23:3) [produces a Mamzer], these are the words of Rabbi Akiva. Shimon HaTimni says: [Relations with] anyone with whom one is liable to Karet [excision] at the hands of Heaven [produces a Mamzer], and the law follows his approach. Rabbi Yehoshua says: [Relations with] anyone with whom one is liable to capital punishment [produces a Mamzer]. Rabbi Shimon ben Azzai said: I found a genealogical scroll in Jerusalem and [the following] was written in it: So-and-so is a Mamzer [as the product of a forbidden union with] a married woman, which supports the position of Rabbi Yehoshua. If one's wife died, he is permitted to her sister; if one divorced [his wife] and she died, he is permitted to her sister. If she [his former wife] married another man and then died, he is permitted to her sister. [If] his Yevama died, he is permitted to her sister. [If] he underwent Chalitzah from her and she died, he is permitted to her sister.
