(Vayikra 25:37: "Your money you shall not give him on interest, and on increase you shall not give your food."): From "your money," I derive: your money, but not that of others (i.e., gentiles); "your food," but not that of others. — But perhaps (the inference should be) "your money," but not that of ma'aser (the tithe); "your food," but not that of beasts! — (No, for "interest of money" (Devarim, Ibid.) includes money of ma'aser (as interdicted); "interest of food" includes food of beasts. This tells me only of interest of money and interest of food (as interdicted). Whence do I derive the same for any kind of interest? From (Ibid.) "interest of anything that can be (construed as) interest."
