[from the fact] that in one case  [there are] two [advantages]  and in the other  [only] one?  — The very [law of a son's precedence in the case of the redemption of a] field of [his father's] possession was deduced by the Tanna from this very argument, viz., 'Surely levirate marriages only take place where there is no son, but where there is a son there is no levirate marriage'! [But why not] say [thus]: 'His kinsman,  refers to the father. This teaches that a father takes precedence over a daughter.  One might [assume] that he [also] takes precedence over [a] son, it was therefore expressly stated that is next [to him],  [which implies,] he who is nearest takes the precedence'? — Since in respect of levirate marriages a son and a daughter have the same  standing, a son and a daughter must have the same standing in the case also of inheritance.  [Why again not] say [thus]: 'His kinsman,  refers to the father. This teaches that a father takes precedence over the [dead man's] father's brothers. One might [assume] that he also takes precedence over brothers, it was therefore expressly stated, that is next,  [which implies], he who is nearest takes the precedence'? — The father's brothers do not require any Scriptural text;  [for] from whom  do the father's brothers derive their right? From the father; should [then] the brothers of the father inherit when the father [himself] is alive! But, surely, the Scriptural verses are not written in this [order], for it is written, And if his father have no brethren etc.!  — The verses are not written in [the proper] order  [of succession]. The following Tanna derives it  from the following: For it was taught: R. Ishmael, son of R. Jose, gave the following exposition: [It is written,] If a man die, and have no son, [then ye shall cause his inheritance to pass unto his daughter].  [This implies that] where there is a daughter the inheritance is passed from the father,  but no inheritance is passed from the father, where there are [only] brothers. But [why not] say [thus]? Where there is a daughter the inheritance is passed from the brothers,
