Midrash sa Mikas 7:20: Vayikra Rabbah, Midrash Tanchuma Buber, Midrash Tanchuma & Midrash Tehillim

Rabbi Avin began in the name of Rabbi Berekhya the Elder: “You then spoke in a vision to Your pious ones, [saying: I aided the mighty one; I raised the one chosen from the people]” (Psalms 89:20) – this is speaking of Abraham, to whom He spoke with speech and in vision. That is what is written: “After these matters, the word of the Lord came to Abram in a vision, saying” (Genesis 15:1). “To Your pious ones [laḥasidekha]” – “give truth to Jacob, kindness [ḥesed] to Abraham” (Micah 7:20). “Saying: I aided the mighty one” – as he killed four kings in one night. That is what is written: “He deployed against them at night…[and smote them and pursued them until Ḥova]” (Genesis 14:15). Rabbi Yitzḥak said: Do you have a person who pursues the dead, as it is stated: “And smote them and pursued them until Ḥova”? Rather, it teaches that the Holy One blessed be He was killing and Abraham was pursuing. “I raised the one chosen from the people” – this is Abraham, who was chosen by the Holy One blessed be He, as it is stated: “Who has chosen Abram” (Nehemiah 9:7).
Another matter: “You then spoke in a vision to Your pious ones” (Psalms 89:20) – this is speaking of David, to whom He spoke with speech and in vision. That is what is written: “In accordance with all these matters, and in accordance with this entire vision, so Natan spoke to David” (II Samuel 7:17). “To Your pious ones [laḥasidekha]” – as it is stated: “Protect my soul, for I am pious [ḥasid]” (Psalms 86:2). “Saying: I aided the mighty one” (Psalms 89:20) – Rabbi Abba bar Kahana said: David waged thirteen wars, and the Rabbis say: Eighteen, and they do not disagree. The one who said thirteen, they were for the needs of Israel. The one who said eighteen, they were five for his own needs and thirteen for the needs of Israel. “I raised the one chosen from the people” (Psalms 89:20) – as it is stated: “He chose David His servant…” (Psalms 78:70).
Another matter: “You then spoke in a vision” (Psalms 89:20) – this is speaking of Moses, to whom He spoke with speech and in vision, as it is stated: “Mouth to mouth I will speak to him, [and a vision]” (Numbers 12:8). “To Your pious ones” (Psalms 89:20) – because he was from the tribe of Levi, as it is stated: “Your Tummim and Your Urim for Your pious one” (Deuteronomy 33:8). “Saying: I aided the mighty one” (Psalms 89:20) – this accords with that which Rabbi Tanḥum bar Ḥanilai said: The way of the world is that a burden that is difficult for one is easy for two; [one that is difficult] for two is easy for four. But can a burden that is difficult for six hundred thousand be easy for one? All of Israel was standing before Mount Sinai and saying: “If we continue to hear [the voice of the Lord our God any more, we will die]” (Deuteronomy 5:22), and Moses was hearing the voice of the divine speech himself, and he lived. Know that it is so, as from all of them, the divine speech called only to Moses, as it is stated: “He called to Moses.” “I raised the one chosen from the people” (Psalms 89:20) – as it is stated: “Were it not for Moses His chosen one” (Psalms 106:23).

A certain Cuthean (i.e., a Samaritan) came and questioned R. Meir. He said to him: Do you not say that indeed your ancestor Jacob is truthful, since it is written (in Micah 7:20): YOU GIVE TRUTHFULNESS TO JACOB …? <The Cuthean> said to him: He separated out the tribe of Levi <as a tithe> for the tribes, <i.e.,> one out of ten. Should he not have separated out <a tithe> from two more <tribes>? He said to him: You have said that there were twelve, but I say that there were fourteen, as stated (in Gen. 48:5): EPHRAIM AND MANASSEH SHALL BE MINE LIKE REUBEN AND SIMEON. He said to him: So here there is support for it. You have added standing grain. Have you added water? He said to him: Do you not admit that there are four matriarchs? [Take away from them the four firstborn (of Jacob's four wives),] since the firstborn is not tithed. Why? Because he is holy, and something holy does not redeem for use something <else that is> holy. He said to him: It is good for your people that you are among them. (Prov. 6:20:) AND DO NOT FORSAKE THE TORAH OF YOUR MOTHER (immekha), <i.e.,> your people (ummatekha). That is what David said (in Ps. 40:9 [8]): TO CARRY OUT YOUR WILL, MY GOD, IS MY DESIRE, <FOR YOUR TORAH IS WITHIN MY BELLY>. R. Aha [bar Ulla] said: Is there Torah within the belly? And is it not so written (in Jer. 31:33): AND UPON THEIR HEART (not their belly) I WILL WRITE IT? It is simply that David said: May a curse come upon me, if something goes down into my belly, except when it is tithed. This is what is written (in I Chron. 27:25): AND OVER THE TREASURIES OF THE KING WAS AZMAVETH BEN {AZRIEL} [ADIEL]. AND OVER THE TREASURIES IN THE COUNTRY, {IN THE VINEYARDS, IN THE MOUNTAINS,} [IN THE CITIES, IN THE VILLAGES,] AND IN THE TOWERS WAS {JOHANAN} [JONATHAN] BEN UZZIAH.³²In other words, David was concerned enough about tithes to appoint overseers. For that reason Moses warned Israel (in Deut. 14:22): YOU SHALL SURELY TITHE.

Another explanation (of Deut. 14:22), “You shall tithe, tithe.” This is related to the verse (in Is. 24:5), “And the earth was distorted under its inhabitants, because they transgressed Torahs;¹⁷Torot. Such a literal translation is required by the midrash. In the biblical context the word denotes something more general, such as teachings. they violated a statute; [they broke an eternal covenant].” R. Isaac said, “You have already been false to it, and [so] it is distorted for you. It [may] show you standing grain, but it does not show you a shock of sheaves. It [may] show you [a shock of sheaves, but it does not show you a threshing floor]. It [may] show you a threshing floor, but it does not show you a winnowed heap. Why [not]? (Ibid.:) ‘Because they transgressed Torahs; they violated statutes,’ in that they did transgress two Torahs, the written Torah and the oral Torah; (ibid.) ‘they violated a statute,’ the statute of tithes; (ibid.) ‘they broke an eternal covenant,’ an ancestral covenant.” For that reason Moses warned Israel (in Deut. 14:22), “You shall surely tithe.” (Prov. 6:20:) “My child, keep your father's commandments, [and do not forsake the Torah of your mother].” R. Huna said, “Our earliest ancestors separated out terumot and tithes.” Abraham separated out the great terumah, as stated (in Gen. 14:22), “[Then Abram said unto the king of Sodom,] ‘I have lifted up my hand unto the Lord, God most high.’” A lifting up is nothing but a terumah (rt.: rwm), as you say (in Numb. 18:26), “[Now you shall speak unto the Levites and say unto them, ‘When you receive tithes from the Children of Israel, the tithe that I have given you as your portion,] you shall lift (rt.: rwm) out of it a terumah of the Lord, [a tithe from the tithe].’” Isaac separated out the second tithe, as stated (in Gen. 26:12), “So Isaac sowed on that land and reaped in that year a hundredfold, [for the Lord had blessed him]”; R. Eiba bar Kahana said, “Is it not true that a blessing does not rest on what is measured, on what is weighed, or on what is counted? So why did he measure them? In order to tithe them. This is what is written (ibid.), ‘for the Lord had blessed him.’”¹⁸See Deut. 14:24, which mentions a blessing in the context of the second tithe; therefore, perhaps the blessing of Gen. 26:12 would have been the result of Isaac’s second tithe. Jacob separated out the first tithe, as stated (in Gen. 28:22), “and of all that You give me, I will surely set aside a tithe for You.” A certain Cuthean (i.e., a Samaritan) came and questioned R. Meir. He said to him, “Do you not say that indeed your ancestor Jacob is truthful?” He said [back] to him, “Yes, as it is written (in Micah 7:20), ‘You give truthfulness to Jacob.’” [The Cuthean] said to him, “He separated out the tribe of Levi [as a tithe] for the tribes, [i.e.,] one out of ten. Should he not have separated out [a tithe] from two more [tribes]?” R. Meir said to him, “You have said that there were twelve, but I say that there were fourteen, as stated (in Gen. 48:5), ‘Ephraim and Manasseh shall be mine like Reuben and Simeon.’” He said to him, “So here you are supporting me. You have added flour. Have you added water?” He said to him, “Do you not admit that there are four matriarchs that had four first-borns? Take away from [the fourteen] the four firstborn (of Jacob's four wives), since the firstborn is not tithed. Why? Because he is holy, and something holy does not redeem for use something [else that is] holy.” He said to him, ‘It is good for your people that you are among them.” Hence it is written (Prov. 6:20), “and do not forsake the Torah of your mother (immekha),” [i.e.,] your people (ummatekha). That is what David said (in Ps. 40:9), “To carry out Your will, my God, is my desire, [for Your Torah is within my belly].” R. Aha bar Ulla said, “Is there Torah within the belly? And is it not so written (in Jer. 31:33), ‘and upon their heart (not their belly) I will write it?’ It is simply that David said, ‘May [a curse] come upon me, if something goes down into my belly, except when it is tithed.’ This is what is written (in I Chron. 27:25), ‘And over the treasuries of the king was Azmaveth ben Adiel; and over the treasuries in the country in the cities, in the villages, and in the towers was Jonathan ben Uzziah.’”¹⁹In other words, David was concerned enough about tithes to appoint overseers. For that reason Moses warned Israel (in Deut. 14:22), “You shall surely tithe.”
