Even though Scripture does not mention the World to Come or the Resurrection of the Dead, the sages interpreted the verses such that they would strengthen the belief in the Resurrection of the Dead and that this is not an invention of the sages rather grounded in Scripture. They did so to such extent that they said: "And those do not have a portion in the World to Come: Someone who says that the Resurrection of the Dead is not from the Torah" (Sanhedrin 90a).
The sages gave many interpretations in order to conclude that there is a source for the Resurrection of the Dead in the Torah; and this is one of them. In the book of Mishlei (Proverbs) it is written: "The grave; and the barren womb; the earth that is not satisfied with water; and the fire that saith not: 'Enough.'" (Proverbs 30:16).
One of the sages, Rabbi Tabi, explained as follows: Why did the scripture place sheol (death and burial) adjacent to womb (sexual procreation and birth)? To teach you about the Resurrection of the Dead through an a forteriori argument: if it is true for the womb that the ones that enter do so in silence during the sexual act yet the baby comes out with sounds of cries, how much more so is it true for death and burial which is done amidst the sound of cries, that the dead will come out with sounds of cries. This teaching constitutes a compelling answer to those who claim that the Revival of the Dead is not from the Torah. (Babylonian Talmud, Sanhedrin 92a).
R. Tabi said in R. Josia's name: What is meant by, The grave; and the barren womb; and the earth that is not filled by water (Prov. XXX, 16.): now, what connection has the grave with the womb? But it is to teach thee: just as the womb receives and brings forth, so does the grave too receive and bring forth. Now, does this not furnish us with an a fortiori argument? If the womb, which receives in silence, yet brings forth amid great cries [of jubilation]; then the grave, which receives the dead amid cries [of grief], will much more so bring them forth amid great cries [of joy]! This refutes those who maintain that resurrection is not intimated in the Torah.In my dictionary, refuting means overthrowing someone else's arguments. I guess the fact that it is mentioned in the Gemara makes it true for OJ fundies, regardless of its logic.
