In this week’s Torah portion of Netzavim Moshe memorably tells the Jewish people in perek 30:
|11For this commandment which I command you this day, is not concealed from you, nor is it far away.
|יאכִּ֚י הַמִּצְוָ֣ה הַזֹּ֔את אֲשֶׁ֛ר אָֽנֹכִ֥י מְצַוְּךָ֖ הַיּ֑וֹם לֹֽא־נִפְלֵ֥את הִוא֙ מִמְּךָ֔ וְלֹֽא־רְחֹקָ֖ה הִֽוא:
|12It is not in heaven, that you should say, “Who will go up to heaven for us and fetch it for us, to tell [it] to us, so that we can fulfill it?”
|יבלֹ֥א בַשָּׁמַ֖יִם הִ֑וא לֵאמֹ֗ר מִ֣י יַֽעֲלֶה־לָּ֤נוּ הַשָּׁמַ֨יְמָה֙ וְיִקָּחֶ֣הָ לָּ֔נוּ וְיַשְׁמִעֵ֥נוּ אֹתָ֖הּ וְנַֽעֲשֶֽׂנָּה:
The Medrish Rabba extrapolates on these pesukim that Moshe told the Jewish people that they shouldn’t say another Moshe will come and bring us another Torah from heaven; I therefore am informing you “It is not in heaven” there is nothing left of the Torah that was not given, in heaven. Another interpretation, in the name of Rebbe Chanina, “It” and all its tools were given, which are: humility, righteousness, and uprightness, as well as it’s reward.
The Maharz”u clearly explains the Torah’s concern related in the medrish. “If you think it is possible to receive another Torah since Hashem can do anything, and your evil inclination will convince you to be lenient in fulfilling this Torah, to this I am informing you that all that is called by the name Torah and mitzvah is included in this Torah. And all that the prophets added and prophesied about and all that was prophesied about the future is all an explanation of this Torah which is higher than heaven and more expansive than earth, and deeper than purgatory, for it is the wisdom of The Creator who created everything and with it he keeps everything existing and there is no other way in the world except to cling to this Torah which is our life in this world and the Next World forever and ever. When the medrish writes about ‘another Moshe would get up’ it’s not literally Moshe, rather what it means is a prophet like Moshe, and just as there will be no other Torah, so to no prophet got up or will get up like Moshe. For even Moshiach will not give us another Torah, rather he will only uphold and explain this Torah. When in the Navi it says, ‘That the land will be filled with the knowledge of Hashem’ it is referring to an explanation of this Torah in our hands.” (Click here for Hebrew text.)
Who would imagine that another prophet like Moshe could bring another Torah, possibly bigger and better than this one? But even if it would be true, why wouldn’t everyone still observe what is in this one until then? This Torah is the blueprints of creation and handbook for mankind right now, and Hashem promises so much reward in this world and the next for observing it, and punishment for transgressing it?! Even more so, the Maharz”u says on Rebbe Chanina’s statement, “that all instruments which are used to acquire the Torah and the Torah refines those attributes as it says in the 6th perek of Pirkei Avos, ‘It makes him fit to be righteous, devout, fair and faithful.’ ‘And the Torah clothes him in humility and fear of Hashem etc.’ And one who is crowned with these traits is literally in this world but walking in heaven…!”
If a person is able to attain such pristine character traits from learning and practicing this Torah, and Hashem says this is what will give you a well-meaning life right now, then why wouldn’t you follow it, even if there could be something better in the future?
It must be that this is the trick of the yetzer hara, the evil inclination, that convinces a person that the next time or the next thing will be better so forget about what you have now, therefore Moshe Rabbeinu is saying don’t think Hashem created a situation like this for the evil inclination to creep in and convince you to stop following this Torah, (which actually sounds like if He would have made another Torah for the future we would not have been able to overcome this test and Hashem does not create tests that are impossible to overcome,) therefore Moshe is informing us that this is the only Torah, which will bring you a well-meaning life in this world and take you into the next world, for eternity.
