Baba Basra 73b - Story of Frog (GR"A)

I attached a link, >CLICK HERE< to the commentary of the GR"A on the Aggados of Rabba bar bar Chana. I found it online at hebrewbooks.org and deleted the parts that weren't pertinent (it begins on page 7) and serves as the basis for "the juggler and the king", by the rosh yeshiva of ner yisroel.

The story of the Frog:

Rabba Bar Bar Chana saw a frog that was the size of the city Hagrunya, which was 60 houses. A snake came and ate the frog. A raven came and ate the snake. The Raven then sat on a tree. Come see the strength of the tree. R' Papa Bar Shmuel commented that if he would not have been there, he would not have believed it.

GR"A explanation:

The Midrash says in Shemos, why were the Egyptians punished with frogs? Because they stopped the Jews from studying Torah, who resemble the frog that doesn't stop making noise day and night. A frog is symbolic of a talmid chacham who doesn't stop studying torah. Rabba tells that he saw a "frog" that was as large as a city of 60 houses, meaning that he was an expert in all 60 tractates - the entire shas. A snake came and swallowed the frog. The snake symbolizes the yetzer ha'rah. There are 2 types of yetzer ho'rah: One works on the land focusing on the "amei ha'aretz" and is called a "nachash", the other focuses on the sea, meaning on those who delve into the yam ha'talmud and is called a "tanin". The tanin came to swallow up the talmid chacham and disturb him from his studies. But then, a raven came and swallowed the snake. The raven refers to the talmid chacham who is mean to his children like a raven, being to preoccupied with torah study to provide sufficient parna'sah to his family (based on the gemara in kesubos). Generally the yetzer ho'rah will use the claim of parnasah to disturb the talmid chacham from his studies, therefore it is the one who can behave like a raven that has the ability to swallow the yetzer ho'rah. The gr"a points out that this is meduyak in rashi who writes that the raven is a mother bird. The nature of the mother raven is a polar opposite of other mothers, in that it shows little regard for it's young. That is why it refers to a talmid chacham who ignores his family and delves into torah study. The raven then sits on a tree. The tree symbolizes those who support talmidei chachamim. The "raven" has no parnasah, but Hashem will provide a "tree" for the raven to support him. Come see the strength of the tree. We find both by the brachos of Yakov and the brachos of Moshe that he mentions Zevulun, the supporter, before Yissoscher, the learner. Why? Because the supporter of Torah overcomes the yetzer ho'rah to use his wealth for luxuries on this world, and channels it toward supporting Torah. The one who supports the Talmid Chacham is in many ways greater than the Talmid Chacham because he overcomes his yetzer horah more than the talmid chacham himself. It is for this reason that the angel of Eisav who saw that he could not win out over Yakov, he hit Yakov in the leg. The leg symbolizes the support of the talmid chacham. When the yetzer horah fails with the talmidei chachamim, he sometimes is successful by attacking the supporter of Torah, so that he discontinues support. R' Papa bar Shmuel said that if he didn't see it he would believe it, because in Bavel there weren't any major supporters of Torah. It is only because he was in Eretz Yisroel did he merit to see such strong tree - this level of support for Torah.
