Midrash su Deuteronomio 7:11

Is that so? Did not R. Mair say: "Whence do we know that even a Gentile who is occupied with the study of the Law, is likened to a high-priest? The passage says (Lev. 18, 5) Which if a man do, shall live by it. It does not specify priest, Levite, or Israelite, but states in general if a man, whence it may be inferred that a Gentile, too, who occupies himself with the study of the Law is equal to a high-priest. We must therefore say that they will not be rewarded for the observance equally with those who observe in accordance with their command; as R. Chanina said: "The reward for him who observes that which he is commanded, is greater than to him who observes the same without being commanded." The nations will then plead the following: 'Sovereign of the Universe, has then Israel, who has accepted the Torah, observed it?' To which, the Holy One, praised be He! will respond: 'I testify that Israel did observe the entire Torah.' 'Sovereign of the Universe,' the nations will say, 'is then a father fit to be a witness in the case of his son? Is not Israel called the son of the Eternal (Ex. 4, 22) My son, my first-born, is Israel.' His reply will be: 'Let heaven and earth testify that Israel observed the entire Torah.' Again they will object, saying: 'Sovereign of the Universe! The heaven and earth are also interested in this case, and therefore are not fit to be witnesses, for it is said (Jer. 33, 25) If My covenant be not … the appointed ordinance of heaven and earth, would not be established. And Resh Lakish said: 'What is the meaning of the passage (Gen. 1, 31) And there was evening and there was morning, the sixth day. Why the article Hay in the word Hashishi? From this it may be inferred that the Holy One, praised be He! stipulated with all that had been created during the six days to the effect that if Israel would accept the Torah, well and good, but if not He would return all of them to chaos and ruin.' Then the Holy One, praised be He! will say: 'Men of your nations may come and testify that Israel has observed the Torah. Nimrod may testify that Abraham did not worship idols. Laban may testify that Jacob was not suspected of robbery. The wife of Potiphar may testify that Joseph was not guilty of adultery. Nebuchadnezzar may testify that Chananyah, Mishael and Azaryah did not bow themselves to the image; Darius of Daniel, that he did not abolish prayer; Eliphaz the Themanite, and Bildad the Schuchite, and Zophar the Na'amathite may say of all Israel that they observed all the Laws; as it is said (Is. 43, 9) Let them bring their witnesses, that they may be justified.' They will then exclaim: 'Sovereign of the Universe! give it to us now, and we will observe it!' To which the Holy One, praised be He! will answer: 'He who has prepared on the eve of Sabbath [for the Sabbath] will have to eat, but he who has not prepared, what then will he have to eat on Sabbath? However, I have one easy, meritorious act; it is the Succah, go and perform it.' But how can you say so [that they will be permitted to perform it in the world to come]? Has not R. Joshua b. Levi said: 'What is the meaning of the passage (Deut. 6, 6) Which I command thee this day to do? i.e., this day to do, but not tomorrow to do; this day to do, but not this day to be rewarded (in this world).' We must therefore explain, this, because the Holy One, praised be He! does not deal despotically with His creatures. (Why is it called easy? Because it requires no expense.) Immediately thereupon, everyone of them will prepare a Succah on his roof, and the Holy One, praised be He! will cause the sun to penetrate it. As soon as the sun heats them, they would kick the Succah with their feet, and go away, as it is said (Ps. 2, 3) Let us break their bands asunder, etc. Why cause the sun to penetrate? Have we not said above that the Holy One, praised be He! does not deal despotically with His creatures? This is because Israel has also to go through such inconvenience of the sun when the summer solstice is postponed until the month of Tishri [touching the feast of Tabernacles]. (Ib. b) But did not Raba say that he who is afflicted by performing the command of Succah, is exempt from that obligation? Yea, but not to kick at it. The Holy One, praised be He! will then smile upon them. Said R. Isaac: "There is no smiling with the Holy One, but on that day."

R. Joshua b. Levi said: "What is the meaning of the passage (Deut. 7, 11) Which I command thee this day to do them? To do it today, but not to be rewarded for it today." R. Joshua b. Levi said further: "All the performance of the commandments which Israel observed in this world, will come and testify for them in the world to come, as it is said (Is. 43, 9) Let them bring their witnesses, that they may be justified; and let them hear and say: 'It is truth;' i.e., let them bring their witnesses, refers to Israel. Let them hear and say, 'It is truth,' refers to all other nations."

The reward for the observance of the Torah, however, is bestowed not in this world but in the world-to-come, as Scripture states in the verse: Which I command thee this day to do them (Deut. 7:11); that is, to do them today and not in the world-to-come. “(I command thee) this day to do them, but I do not decree that you should receive the reward for their observance today.” Hence Solomon said (of the woman of valor): Strength and dignity are her clothing; and she laugheth at the time to come (Prov. 31:25); (inasmuch as her reward will be given to her in the time to come).
