I read some where the following quote: "all the other teachings of the prophets can be derived from the Torah, and since the Messiah will reveal all the meanings of the Torah to perfection, the prophetic writings will no longer be needed." I’m wondering if you can clarify for me what it means: thanks

Shalom, Thanks for writing again. The quote you are asking about is as follows “There is an opinion that the only books of the Bible which will be regularly studied in the Messianic Era will be the Five Books of Moses and the Scroll of Esther. The reason for this is that all the other teachings of the prophets can be derived from the Torah, and since the Messiah will reveal all the meanings of the Torah to perfection, the prophetic writings will no longer be needed.” The idea is that in essence the words of the Prophets are “clarifications” of the core teachings found in the five books of Moses. As such, if we could (theoretically) understand the Torah in all it’s depth, we would be able to see in it all the teachings of the prophets. Today this is not possible, but (according to this one Rabbinic teaching) the Messiah himself, being of a level of Torah wisdom beyond anything we have seen until now, will be able to reveal the Torah at such a level. This will leave the later books of the Tanach unneeded. Blessings.
