1 At all times controversies arise on this matter, how the dead shall rise and with what body they shall come? For lo! The body wears out and is corrupted; and the bones also, no doubt, as time lengthens out over them, waste away and are not to be recognised. And when you enter a tomb in which a hundred dead men are buried, you find not there an handful of dust. And thus say those that reflect on these things:— “We know of course that the dead shall rise; but they will be clothed in a heavenly body and spiritual forms. And if it is not so, these hundred dead that were buried in one tomb, of whom after a long time elapses there remains nothing at all there, when the dead shall be quickened, and shall be clothed in a body and rise, unless they shall be clothed in a heavenly body, from whence shall their body come? For lo! There is nothing in the tomb.”
