"And when you bring near" (Leviticus 2:4): when you bring near, doing the matter is optional. Rabbi Yehudah said: from where do we learn that one who says "It is upon me to bring an oven-baked meal-offering" may not bring half loaves and half wafers? Scripture says "an offering of a meal-offering" (Leviticus 2:1): he brings one offering, and he does not bring loaves and wafers together. Rabbi Shimon said: is "offering, offering" stated twice? Only one offering is stated, and within it loaves and wafers are mentioned; say therefore that if he wished to bring loaves he may, wafers he may, half loaves and half wafers he may, and he mixes and takes a handful from both, so that if he took a handful and only one of the two kinds came up in his hand, that is enough. Rabbi Yose son of Rabbi Yehudah said: from where that one who says "It is upon me to bring an oven-baked meal-offering" may not bring half loaves and half wafers? Scripture says "and every meal-offering that is baked in the oven" (Leviticus 2:4 and 7:9); just as the "every" stated below refers to two kinds, so the "every" stated above refers to two kinds. And Rabbi Yehudah holds that Rabbi Shimon spoke well; he would say to you: since it is written "in oil, in oil," it is as if it were written "offering, offering." And Rabbi Shimon holds: had it not written "in oil," I would have said specifically half loaves and half wafers, but loaves by themselves and wafers by themselves, say no; therefore it teaches us otherwise. Rabbi Yose son of Rabbi Yehudah is the same as his father; the difference between them concerns one done after the fact. "Baked in the oven," and not baked in a small stove, and not baked on tiles, and not baked in Arabian kettles. Rabbi Yehudah said: "oven, oven" twice, to render fit what is baked in a small stove. Rabbi Shimon said: "oven, oven" twice, that its dedication be for the sake of an oven.
The Oven-Baked Meal-Offering Brought as One Kind Not Half Loaves and Half Wafers
