Explanation: He did so due to a sealed grave. The Tum'ah breaks through and goes up, like it says in several places.

Question: Graves of Nochrim do not have Tum'as Ohel, for they are not called Adam!

Even Rabanan, who argue with R. Shimon (Yevamos 61a), and say that they have Tum'as Ohel, in any case, in Nazir (54a) we include a grave before Matan Torah only regarding touching;

"Oh b'Kever" includes a grave before Matan Torah. It is included there from a verse written regarding touching.

Answer: Avraham is called "Adam", for it says "ha'Adam ha'Gadol", and similarly regarding Adam ha'Rishon. Therefore, we do not exclude them from the verse "Adam". (See also Tosfos Yevamos 61a DH Kivrei.)

Explanation: E.g. he denied owing and they took from him through witnesses;

However, if he was obligated to swear, and he did not want to swear, rather, he paid, due to this he is not disqualified from judging.

Explanation (Rabbeinu Chayim): Anvag and Anpak are medicinal liquids;

This is Aspargus, about which it says (Berachos 51a) Aspargus is good for the heart, like it connotes in Kidushin (70a);

Here it means that what we call Anvag and Anpak, one must drink the Shi'ur of Antal, which is a Revi'is.

Support: It says in Chulin (94a) that "Anpak" connotes undiluted;

This is Aspargus, like it says in Berachos that we drink Aspargus only undiluted.

Implied question: Why don't we list in Berachos (51a) among five things said about Aspargus that one must drink the Shi'ur of a Revi'is??

Answer: We are not concerned to list what depends on the Shi'ur.

Implied question: It says in Shabbos (109b) "cook them until they are an Anpaka." This connotes that it is a measure!

Answer #1: It means, until they are the amount that one drinks of Anpaka.

Answer #2: Also the Kli is called Anpaka, because they drink that Shi'ur of it.

Explanation: If it was in the east, he can tell him "put it in the west." However, he cannot [tell him to] remove it totally from both directions.

Question: How is there Chazakah for Mazchilah (a long gutterpipe)? When he puts the Marzev (short gutterpipe) on one end of the Mazchilah, also the Mazchilah he must move it and lift one end and lower the other end where he puts the Marzev;

How can we say that the Marzev has no Chazakah, and the Mazchilah has a Chazakah? He will never move the Marzev unless he moves also the Mazchilah!

Answer #1: In any case it has a Chazakah regarding that he need not totally uproot it from its place, the way he must uproot the Marzev.

Answer #2: Since the Mazchilah is level, and one side is no higher than the other side, he never needs to move it from its place, only to seal the side from which he removes the Marzev.

Answer #3 (Rabbeinu Yosef): Marzev has no Chazakah from one direction, for he can tilt the end of the Marzev to the north or south, when it is in the east;

It has a Chazakah from two directions. He cannot force him to remove its end to the other end of the Mazchilah.

Support: R. Chananel explained like this, that if the Marzev is fixed in the middle of the eastern side, the owner of the Chatzer can uproot it from the middle and fix it in a third (i.e. a third of the distance from one end) of the roof or a quarter, and anywhere in that direction that he wants;

However, he cannot remove it to a different direction, since he has a Chazakah.
