Midras Keluaran 18:13: Ein Yaakov (Glick Edition), Bereshit Rabbah, Mekhilta DeRabbi Yishmael & Sifrei Devarim

R. Ami and R. Assi were accustomed to sit between the pillars [of the academy] and every now and then to rap [the bolt of the door] and say: "Is there any one who requires adjustment of a dispute? Let him come in." _ _„R. Chisda and Rabba b. R. "Huna were holding court the entire day and were becoming weak. R. Chiya b. Raba of Difty recited to them the passage: And the people stood about Moses from the morning unto the evening. (Ex. 18, 8.) How can we imagine that Moses was holding court the entire day? When did he study? We must therefore say that a Judge who, even for one hour, passes judgment according to its true equity, is credited by Scripture as if he had become a partner of God in the creation of the world, for it is written here (Ex. 18, 13.) From the morning unto the evening, and it is written, And it was morning and it was evening the first day. [Hence you need not hold court the entire day.] Until when should the work of justice continue? R. Shesheth said: "Until mealtime." Rami b. Chama said: "What is the Biblical passage for it? Woe to thee, O Land. when thy king is low-minded, and when thy princes eat in the morning. Happy art thou, O Land, when thy king is noble-spirited, and thy princes eat at the proper time for strengthening and not for gluttony (Ecc. 10, 16.) i.e., for strengthening of the Torah and not for the gluttony of wine." Our Rabbis taught: "The first hour [of the day] is the time when the Lydians eat; during the second hour robbers eat; during the third hour (rich) heirs eat; during the fourth hour laborers eat; during the fifth hour the people in general eat." Is this so? Has not R. Papa said that during the fourth hour the people in general eat? We must therefore say that "During the fourth hour the people in general eat; during the fifth hour laborers eat; during the sixth hour scholars eat; from this hour on eating is like throwing a stone into a skin-bottle (it has no effect)." Abaye said: "This applies only to a case where nothing was tasted in the morning; but if something were tasted in the morning then it matters little [how late he eats]."

Rabbi Yishmael asked Rabbi Akiva, saying to him: ‘Because you studied under Naḥum of Gam Zo for twenty-two years, [who taught:] The words akh and rak are restrictive expressions, et and gam are inclusive expressions, [I ask you:] What is the meaning of the et that is written here [twice]?’⁵⁵Et hashamayin ve’et haaretz. He said to him: ‘Had it been stated: “In the beginning God created heavens and earth [bereshit bara elohim shamayim vaaretz]” – we might have said that the heavens and the earth are deities.’⁵⁶It could have been interpreted: ‘God, who is heavens and earth, created.’ The word et, however, indicates that what follows is the direct object of the verb.
He [Rabbi Yishmael] said to him: “For it is not an empty matter for you [mikem]” (Deuteronomy 32:47) – if it is empty, it is because of you [mikem],⁵⁷If you find something in the Torah that appears devoid of significance, it is because of your own ignorance. because you do not know how to expound, because you do not exert yourself in its regard. “As it [the Torah] is your life” (Deuteronomy 32:47) – when is it your life? It is when you exert yourself in its regard. Rather [the explanation is]: “et hashamayim” – to include the sun, the moon, and the constellations; “ve’et haaretz” – to include trees, vegetation, and the Garden of Eden.
Rabbi Tanḥuma said in the name of Rav Huna: “Betzalel, son of Uri, son of Hur, of the tribe of Judah, did everything that the Moses commanded him” is not stated, but rather, “everything that the Lord commanded Moses” (Exodus 38:22). Even matters that he [Betzalel] did not hear from his teacher, his perception corresponded to what was stated to Moses at Sinai. Rabbi Ḥonya said in the name of Rabbi: “The Torah of truth was in his mouth” (Malachi 2:6) – these are matters that he heard directly from his teacher.⁵⁸The following line should be added here (Matnot Kehuna): “and falsehood was not found on his lips” (Malachi 2:6) – these are matters that he did not hear from his teacher. The Rabbis say: “For the Lord will be your hope [bekislekha]” (Proverbs 3:26) – even matters that you are a fool [kesil] in their regard, “He will protect your foot from being ensnared” (Proverbs 3:26).⁵⁹If you make a concerted effort to understand, God will assist you, even regarding matters that you do not know about, so that you will not be caught up in any misstep. Rabbi Dosai said: From promulgating [mistaken] teachings. Rabbi Abahu said: From transgressing. Rabbi Levi said: From malevolent spirits. Rabbi Avdimus said: If you gave charity from your purse [kis-lekha], the Holy One blessed be He will protect you from being charged unjust security taxes, fines, head taxes, and property taxes.

(Exodus 18:13) "And it was on the morrow that Moses sat to judge the people.": on the morrow of Yom Kippur (after Moses had descended with the second tablets.) "from morning to evening": Now did Moses judge Israel from morning to evening? Do not judges judge only until the time of eating? We are hereby taught that if one judges a judgment of truth Scripture accounts it to him as if he were a partner with the Holy One Blessed be He in the creation, of which it is written (Genesis 1) "and it was evening and it was morning."
