(Devarim 14:9) "This may you eat … (12) and this you may not eat, etc.": R. Akiva said: Was Moses a hunter or an archer (that he knew the signs of all the animals in creation)! Let this serve as a riposte to those who say there is no Torah from Heaven!
(דברים יד ו) אַךְ אֶת זֶה לֹא תֹאכְלוּ וְגוֹ׳ הַשְּׁסוּעָה, אָמַר רַבִּי עֲקִיבָה: וְכִי מֹשֶׁה קְנִיגִי הָיָה אוֹ בַּלִּיסְטְרִי הָיָה? אֶלָּא מִכָּן תְּשׁוּבָה לָאוֹמְרִים אֵין תּוֹרָה מִן הַשָּׁמַיִם.
