(Mishnah): The following are vows of exaggeration - 'if I did not see on this road k'Olei (the number of people who ascended to Eretz Yisrael after leaving) Mitzrayim', or 'if I did not see a snake like the beam of an olive press.'

How are Nidrei Shegagos? 'If I ate' or 'if I drank (I forbid...)', and [later] he remembered that he ate or drank'

'That I will not eat and I will not drink', and he forgot and ate or drank.

'Konam my wife may not benefit from me, for she stole my wallet or hit my son', and later he found out that she did not hit him, and he found out that she did not steal it.

If one saw people eating his figs, and said 'the figs are forbidden to them like a Korban'; and it turns out that his father or brothers were [eating], and there were others with them - Beis Shamai say, [his father and brothers] are permitted, and those with them are forbidden;

Beis Hillel say, these and these are permitted.

(Gemara) Question: Is it not possible that k'Olei Mitzrayim passed [on the road]?! When king Lulainus descended to there (Bavel), 1,200,000 [soldiers, twice k'Olei Mitzrayim] descended with him!

Answer: The case is, [he means that] he saw [so many people] at once. (The road is narrow, so one cannot see so many people on it at once.)

Question: (Perhaps it is true that he saw such a giant snake!) There was a snake in the days of Shvor Malka that swallowed camels and wagons!

When they wanted to kill it, they brought stuffed camel hides and filled them with straw, and put coals in them, and it swallowed them and died.

R. Yudah bar Pazi: I saw the skin of a snake that was tanned and covered eight benches.

R. Shmuel bar Yakov: I saw the skin of a snake that covered the king's wagons (which are humongous).

Answer (Shmuel): [He swears that] it was square.

Question: If [he swears that] it was square, even if it is small (this is Havai! He should say just 'it was square'! Why does it say like a beam of an olivepress? We explained this like CHON ASHIR on the Mishnah.)

Answer (R. Masniyah): (Indeed, it is even if it is small.) The Tana normally mentions only big things;

Our Mishnah mentions a camel flying in the air. Why didn't it teach a mouse flying in the air? (Also this is impossible! Rather, the Tana mentions big things. ALEI TAMAR Shevu'os 3:8 - it mentioned a camel, for people call a very fast camel "a flying camel." Perhaps we ask that it should have mentioned a mouse, for Tinshames (a kind of bat) looks like a mouse, and it flies (RASHI Vayikra 11:8) - PF.)

(Beraisa - R. Shimon ben Gamliel): There is no square [creation] from the six days of creation.

Question (R. Berachiyah - Mishnah): The size of a Baheres must be [at least] a square Italki bean.

Answer #1 (R. Yosna): The Mishnah shows that the bean is not square! Why did it need to teach "square"? Rather, one squares the bean (makes a square as long as the length of the bean - MELECHES SHLOMO Nega'im 6:1, from the ROSH).

Question: A Kan'ah (PNEI MOSHE - a kind of Sheretz, it is square)!

Answer: It is full of knots. (It is not a smooth square.)

Question: The knee of a Ya'al (a Chayah, it is square)!

Answer #1: It is round at the bottom.

Answer #2 (also for an Italki bean): Some say that R. Shimon ben Gamliel said only about Beriyos (Ba'alei Chayim. There can be square Peros or limbs.)

Support (Beraisa): There are square foods, but not square Beriyos.
