Tertullian

Let me dispel at once the … assertion that the prophets make all their announcements in figures of speech. Now, if this were the case, the figures themselves could not possibly have been distinguished, inasmuch as the verities would not have been declared, out of which the figurative language is stretched. And, indeed, if all are figures, where will be that of which they are the figures? How can you hold up a mirror for your face, if the face nowhere exists? But, in truth, all are not figures, but there are also literal statements; nor are all shadows, but there are bodies too. We have prophecies about the Lord himself even, which are clearer than the day. For it was not figuratively that the Virgin conceived in her womb.… Not even of his mighty works have [the prophets] used parabolic language. Or else, were not the eyes of the blind opened? Did not the tongue of the mute recover speech? Did not the relaxed hands and palsied knees become strong, and the lame leap like a deer? No doubt we are accustomed also to give a spiritual significance to these statements of prophecy, according to the analogy of the physical diseases that were healed by the Lord. But still they were all fulfilled literally, thus showing that the prophets foretold both senses, except that very many of their words can be taken only in a pure and simple signification and free from all allegorical obscurity.
