In Shemos, Perek Chof Ches, posuk tes vov, the Torah tells us that the Choshen was made via artisan sewing. In posuk lamed the Torah says that they inserted the Urim VeTumim in the Choshen.
The question arises, how could one pasken based on the Urim VeTumim? The Gemara in Bava Metziya, daf nun tes, amud bais says that the Torah is not “bashomayim,”(in heaven) therefore we don’t pasken based on a bas kol.
The Gemara in Temura, daf tes zayin, amud alef says that three thousand halachos were forgotten during the period of mourning for Moshe Rabbeinu. Klal Yisro
There are a number of tirutzim explaining how we could rely on the Urim VeTumim. The first tirutz is that when it comes to a halacha one can’t pasken based on the Urim VeTumim. On the other hand, when it comes to figuring out facts of the metziyus of what actually took place or will take place, we are able to ask the Urim VeTumim. A proof to this can be brought from the Gemara in Eiruvin, daf samech daled, amud bais where Rabban Gamliel gave a non-Jew a gift because he was able to see with ruach hakodesh that the goy was not an idol worshipper. From here we see that when it comes to be mevarer the metziyus one may rely on the Urim VeTumim and there is no problem of “Torah is not bashomayim.”
Another tirutz can be brought from learning the ins and outs of a din torah. In the same way the baalei dinin in a din torah are able to accept relatives as witnesses, they can also accept the Urim VeTumim as the deciding factor in their din torah. A proof to this can be found in Meseches Meggilah, daf yud daled, amud alef. The Gemara says that Devorah the nevia used to sit outside under a tree so as not to be oveir on yichud while she judged Klal Yisroel. How was she able to judge Klal Yisroel if a woman is not kosher to be a judge? Tosfos and Ritva answer that the baalei denim accepted Devorah as their judge. The same logic was used for the Urim VeTumim.
A third tirutz can be explained as the Even Ezra expounds on the above posuk that the Urim VeTumim did not pasken. The Urim VeTumim revealed the reasoning of the psak to the judges or the neviim, but the psak was rendered via the shofet or navi. The Urim VeTumim only revealed the ta’am of the psak, but the psak still had to be given by the judge or prophet.
The final tirutz is based on the Chassam Sofer who says that when there is a safek, we pasken min hashomayim. Where there is a machlokes we discount the bas kol and do not rely on the Urim VeTumim. In a case where the navi or the shofet have a safek and don’t know what to pasken, then we actually do rely on the Urim VeTumim. This will explain why in the times of Ezra and Nechemya they verified from the Urim VeTumim who had yichus and who was not a Kohen. When Moshiach comes Eliyahu Ha
May we be zocheh to have the Urim VeTumim and have clarity in our learning and psak.
