Midrasch zu Schemot 17:1

(Deut. 14:22:) YOU SHALL SURELY TITHE <ALL>. Moses said: Sovereign of the World, does it follow from here that one takes out a tithe? The Holy One said to him (in Job 8:8, 10): SO PLEASE ASK A FORMER GENERATION, AND CONFIRM THE RESEARCH OF THEIR ANCESTORS…. WILL THEY NOT INSTRUCT YOU AND TELL YOU….? How so? (I Chron. 1:1:) ADAM, SETH, ENOSH. From Adam up to Noah there are ten generations,¹I.e., Adam, 2. Seth, 3. Enosh, 4. Kenan, 5. Mahalalel, 6. Jared, 7. Enoch, 8. Methuselah, 9. Lamech, and 10. Noah. See Tanh., Gen. 9:1; TDER (16), p. 80 (Friedmann). and I took the tenth.²Probably Noah (Gen. 6:9), but possibly Enoch (Gen. 5:21). See PRK 23:10. From Noah to Abraham there are ten generations,³I.e., 1. Noah, 2. Arpachshad, 3. Shelah, 4. Eber, 5. Peleg, 6. Reu, 7. Serug, 8. Nahor, 9. Terah, 10. Abraham. and I took the tenth, which was Abraham. So it is therefore written (in Job 8:10): WILL THEY NOT INSTRUCT YOU AND TELL YOU to take out one tenth? (Deut. 15:20:) YEAR BY YEAR. If you have taken out a tithe during a given year, you gain merit for another year. R. Abba bar Kahana said: The importance of tithes is <mentioned> throughout all the Torah (in the Law, in the Prophets, and in the Writings). It is written (in Deut. 6:16): DO NOT PUT THE LORD YOUR GOD TO THE TEST <AS YOU PUT HIM TO THE TEST THROUGH A TAX (MSH)>.⁴So the midrash understands this verse. Since Deut. 6:16 refers to an incident at Massah (MSH) in Exod. 17:1–7, biblical translations render the bracketed clause to mean, AS YOU PUT HIM TO THE TEST AT MASSAH. Exod. 17:1–7 also explains in vs. 7 that MASSAH means “test.” The midrash, however, either revowels MSH as MISSAH, a word which means “tribute,” “contribution,” or “quota,” in this case the tithe, or perhaps understands the name as a form of mas, which had come to mean “tax.” Also in reference to tithes it is written (in Mal. 3:10): [BRING ALL THE TITHE <INTO THE STOREHOUSE, THAT THERE MAY BE FOOD IN MY HOUSE>]. SO PLEASE TEST ME IN THIS, <SAYS THE LORD OF HOSTS>. And who tested the tithes? The generation of Hezekiah, as stated (in II Chron. 31:9–10): THEN HEZEKIAH {THE KING} QUESTIONED <THE PRIESTS AND THE LEVITES> ABOUT THE HEAPS (of produce). SO THE CHIEF PRIEST AZARIAH OF THE HOUSE OF ZADOK SPOKE [UNTO HIM] <AND SAID: EVER SINCE PEOPLE BEGAN TO BRING THE TERUMAH (i.e., the priestly tithe on produce) TO THE HOUSE OF THE LORD,> WE HAVE EATEN {AND HAVE DRUNK} [AND HAVE BEEN SATISFIED], WHILE LEAVING OVER <FOOD IN GREAT AMOUNTS>. Why? (Ibid., cont.:) BECAUSE THE LORD HAS BLESSED HIS PEOPLE. The Holy One said: In this world I have blessed one generation, but hereafter in the world to come, I am blessing <all the generations of> Israel, as stated (in Jer. 31:22 [23]): AGAIN THEY SHALL SAY THIS THING {ON THE MOUNTAIN OF THE LORD, IN JERUSALEM, AND IN ALL THE CITIES OF JUDAH} [IN THE LAND OF JUDAH AND ITS CITIES, WHEN I RESTORE THEM AS BEFORE]: MAY THE LORD BLESS YOU, O HABITATION OF {RIGHTEOUS HOLINESS} [RIGHTEOUSNESS], O HOLY MOUNTAIN.

God led them not by the way of the Philistines (ibid. 13:17). He guided them in the manner indicated in the verse Thou didst lead Thy people like a flock (Ps. 77:21), and as in the verse By day also He led them by a cloud (ibid. 78:14). By the way of the land of the Philistines, although that was near. The word near indicates that the promise the Holy One, blessed be He, had made to Abraham was soon to be fulfilled. Near also implies that it was the nearest way to return to Egypt. Furthermore near relates to the oath Abraham had sworn with Abimelech. Now therefore, swear unto me here by God, that thou wilt not deal falsely with me, or with my son, nor with my son’s son (Gen. 21:23) was near fulfillment, even though his grandson had not yet been born. Furthermore, near implies that the previous war was too recent to risk another.¹The “previous war” being the one referred to in the continuation of the verse: lest … the people repent when they see war (Exod. 17:1). A tradition exists that the descendants of Ephraim left Egypt before the designated time and 300,000 were killed. See Ginzberg, Legends, vol. 3:8–9. Only ten escaped. Another explanation of Although that was near. It was too close to the time in which the Canaanites had obtained the land, for it is written: And in the fourth generation they shall come back hither (ibid. 15:16), and the fourth generation had not yet come. God led the people about by the way of the wilderness (Exod. 12:18). The Holy One, blessed be He, said: If I lead them into the land by the most direct route, they will each take possession of a field and a vineyard and neglect the law. Therefore I will lead them through the wilderness for forty years and cause them to eat the manna and drink the water of the well so that the law may penetrate into their very beings.

We are taught Rabbi says: "Circumcision is so important that although there is no one greater in meritorious deeds than Abraham our patriarch, nevertheless he was not called perfect but through the act of circumcision, as it is said (Ex. 17, 1) Walk before Me, and be thou perfect, and again it is written. And I will make My covenant between Me and thee. Another reason may be given why circumicision is so important, because it equals in importance all commandments of the Torah. as it is said (Ex. 34, 27) For after the tenor of these words have I made with thee a covenant and with Israel. Another reason may be given why circumcision is so important, because if not for circumcision heaven and earth would not have been in existence, as it is said (Jer. 33, 25) Had My Covenant not been by day and night, I should not have appointed the heaven and earth." This differs with the opinion of R. Elazar, for R. Elazar said: "Torah is so important that if not for the Torah, heaven and earth would not have been in existence, as it is said, Had My covenant not been by day and night," etc. R. Juda said in the name of Rab: "At the time when the Holy One, praised be He! said: Walk before Me and be thou perfect, Abraham began to tremble and said, 'Perhaps there is something disgraceful within me.' But as soon as God said to him (Ib., ib., 2) And I will make My covenant between Me and thee, he immediately calmed himself (Ib., ib., 15, 5) And he brought me forth abroad. Abraham said before him: "Sovereign of the Universe, 'I have consulted my horoscope and have found that I am incapable of having a son except the one Ishmael." Whereupon the Holy One, praised be He! said unto him: "Cease thy esterylogical speculation, for Israel stands not under planatory influence."
