In the Bavli, Berakhot 15b, R' Tavi explains Proverbs 30:15-16 in such a way that it implies a resurrection of the dead, and concludes that this is a response to those who say that there is no reference to the resurrection of the dead in the Torah. But is Proverbs part of the Torah?
If we consider the book of Proverbs to be part of the Torah, then surely we can also consider the books of Isaiah and Daniel to be part of the Torah, and they mention the resurrection of the dead explicitly:
Isaiah 26:19, "Your dead shall live, their corpses shall rise. O dwellers in the dust, awake and sing for joy!"
Daniel 12:2, "Many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt."
If references like these can be considered "part of the Torah", then why do we need to find clever interpretations of non-explicit passages in order to answer those who claim that the Torah contains no reference to the resurrection of the dead? And if the books of Isaiah and Daniel are not to be considered "part of the Torah", why is the book of Proverbs?
