Talmud do Przysłów 8:21

⁷⁹Cf. Babli Sukkah 28a. Hillel the Elder had eighty pairs of students. The greatest among them was Jonathan ben Uzziel, the least important Rabban Joḥanan ben Zakkai. Once he fell sick and all came to visit him. Rabban Joḥanan ben Zakkai waited in the courtyard. He said to them, where is the least important among you who is a head in wisdom and a head for generations? Unnecessary to speak of the greatest among you! They said, he is in the courtyard. He said to them, let him enter. When he entered, he said to them “to let my lovers inherit substance; their treasuries I shall fill.⁸⁰Prov. 8:21. Cf. Mishnah Uqeṣin 3:12.”

Rabban Yohanan ben Zakkai received from Hillel and Shammai. Hillel the Elder had eighty students. Thirty of them were worthy of having the Divine Presence rest upon them like Moses our teacher; it was only that their generation was not fit for it. Thirty of them were able to make adjustments to the calendar. And twenty of them were average.
The greatest of them all was Yonatan ben Uziel and the lowest of them was Rabban Yohanan ben Zakkai. And they said about Yohanan ben Zakkai that he was not ignorant of anything: Scripture; Mishnah; Talmud, including Halakhot, Aggadot, and all kinds of other material; grammatical analysis of the Torah; analysis of the scribal traditions; and all the interpretive traditions of the sages. He did not leave aside anything in the Torah, in order to fulfill the words (Proverbs 8:21), “I give substance to those who love me; I will fill their treasuries.”
