JUSTIN MARTYR:
You [Trypho, a Jew] object that Noah was ordered to make a distinction between the herbs, because we do not now eat every kind of herb. Such a conclusion is inadmissible. I could easily prove, but we will not spend the time now in doing so, that every vegetable is an herb and may be eaten. Now, if we make a distinction between them and refuse to eat some of them, we do so not because they are common and unclean but because they are bitter, or poisonous or thorny.
