Rabba bar Bar Chana said: Once I saw a frog that was as big as the town of Hegronia. And how big was the town of Hegronia? Sixty houses. A snake came and swallowed it (Commentary : this shows how BIG he was. A female crow swooped down and ate the snake and then flew up and sat on a branch of a tree. Come and see: How great is the strength of that tree. ---- Another Rabbi upon hearing this story commented: "If I wouldn't have been there myself, I wouldn't have believed it."
