A child of the poor, who has learned Tanakh, Mishnah, Midrash, Halakhah, and Aggadah, but has no knowledge. What is the pure fish? A child of the rich, who has learned Tanakh, Mishnah, Midrash, Halakhah, and Aggadah, and has knowledge. What is the fish from the Jordan? A scholar who has learned Tanakh, Mishnah, Midrash, Halakhah, and Aggadah, but does not know how to comment upon it. What is the fish from the Great Sea? A scholar who has learned Tanakh, Mishnah, Midrash, Halakhah, and Aggadah, and knows how to comment upon it.
