Commentary for Bava Batra 5:11

So that I can hide from you: Private matters. But a courtyard divided by the two of them is fixed for the use of each one in his section at all times; so they do not do private matters in it.

Since they wished to divide [it]. But later it challenges, "Why was he speaking about, 'If they wished?' Even if they did not [both] wish," they can compel one another.

They build a wall of stones.

A wall: A wall of stones. And this is in a courtyard subject to the law of division; so they split it [even] against their will.

The reason is that they wished: And they stipulated that it be divided with a wall of stones. Behold, if they did not wish [it], they only obligate him with a mere bordermark.

As people say, etc.: This is a resolution (an answer).

Is not subject to the law of division: [As it does not consist of] at least eight ells. [So] they do not divide it.

What is it teaching us? That when it is not subject to the law of division: [The question is asked] even though it is teaching that it is considered damage. This is [the question's] explanation: What is it teaching us by that which it is speaking about when it is not subject to the law of division? Let it make us understand about when it is subject to the law of division that [even though they did not want] (when they wanted), they must divide it. It is [however still] a wonder! Behold it is teaching us that even when it is not subject to the law of division - that it can be said that [when] one [agreed to a partition, but] did not agree to making a wall, [he must still do so], as it explained earlier.

And sacred writings: A Torah scroll which is in one town. And likewise, Prophets and Writings that are written on parchment like a Torah scroll.
