"And let it teach here: A man acquires" - so that it would be taught in the language of the Sages, [namely:] "A man betroths."

But let it be taught - In this case the man acquires in three ways.

And she becomes acquired - She for herself in two ways: And it answers, on account of there being in those two ways the death of the husband.

One examines a zav - with regard to food and with regard to drink, with regard to sickness, with regard to jumping, with regard to a burden, and with regard to a[n arousing] sight, and with regard to the thought [of a woman], in case he saw [the discharge] due to one of these [factors]. [Any of those] would make him a victim of circumstances beyond his control, and [thereby] pure. As the Torah says, "from his flesh" [Leviticus 15:2] -- [that is], on its own, and not due to [other] circumstances beyond his control. Whereas a woman becomes impure even due to circumstances beyond her control, as is stated in chapter "Samaritan Girls" [Niddah 36b:13]: "When the verse states: “And if a woman has an issue of her blood" [Leviticus 15:25], it is referring to circumstances beyond her control.

And [the Gemara] asks, what is the reason that the mishna teaches "Three" [shalosh, in the feminine] - are you saying because it wanted to teach "ways"?

Let it teach instead the word: "Matters" and let it teach three [shelosha, in the masculine] - as is typical for the Gemara.

And it was taught two because of one? - Surprising! To change the language (from male to female) of 'Money' and 'Document' for the sake of 'Intercourse'? He should follow the majority.

Who is this - That taught (in this) language (the way) of betrothing a woman? It is Rabbi Shimon, who says the way of the world applies to them.

A Loss - (Referring to) one of his Ribs.

In three ways - just as with [other] trees, the laws of orlah and the fourth-year sapling apply to [an etrog tree]. With regard to the shemitta year, its fruit is reckoned, as for [other] trees, according to the time of its formation, and not according to the time it is picked, as with vegetables.

And corresponding to those of a vegetable in one way - namely, that [the reckoning of its year for the purpose of] its tithes [are according to the time of] its harvesting. For the purpose of tithes, it is not reckoned according to the [year] of its [fruit's] formation like other trees, but rather according to the year in which it was picked, as with vegetables, for which the reason will be given below. Tithes differ over the course of the years: in the first year of the shemitta cycle, the first and second tithe [are taken], and so too in the second [year]. But in the third [year] -- the first tithe and the tithe of the poor. If the [fruit] formed in the second [year] and was picked in the third [year] -- with other trees, [it would be reckoned] according to [the year of] its formation, whereas the etrog [would be reckoned] according to when it was picked, as with a vegetable.
