Perhaps it is because the plant is akin to virginity that it is called bramble and agnos; bramble, because of its strength and firmness against pleasures; agnos, because it always continues chaste. Hence the Scripture relates that Elijah, fleeing from the face of the woman Jezebel,  at first came under a bramble, and there, having been heard, received strength and took food; signifying that to him who flies from the incitements of lust, and from a woman -- that is, from pleasure -- the tree of chastity is a refuge and a shade, ruling men from the coming of Christ, the chief of virgins. For when the first laws, which were published in the times of Adam and Noah and Moses, were unable to give salvation to man, the evangelical law alone has saved all.
And this is the cause why the fig-tree may be said not to have obtained the kingdom over trees, which, in a spiritual sense, mean men; and the fig-tree the command, because man desired, even after the fall, again to be subject to the dominion of virtue, and not to be deprived of the immortality of the paradise of pleasure. But, having transgressed, he was rejected and cast far away, as one who could no longer be governed by immortality, nor was capable of receiving it. And the first message to him after the transgression was preached by Noah,  to which, if he had applied his mind, he might have been saved from sin; for in it he promised both happiness and rest from evils, if he gave heed to it with all his might, just as the vine promises to yield wine to those who cultivate it with care and labour. But neither did this law rule mankind, for men did not obey it, although zealously preached by Noah. But, after they began to be surrounded and drowning by the waters, they began to repent, and to promise that they would obey the commandments. Wherefore with scorn they are rejected as subjects; that is, they are contemptuously told that they cannot be helped by the law; the Spirit answering them back and reproaching them because they had deserted those men whom God had commanded to help them, and to save them, and make them glad; such as Noah and those with him. "Even to you, O rebellious," said he, "I come, to bring help to you who are destitute of prudence, and who differ in nothing from dry trees, and who formerly did not believe me when I preached that you ought to flee from present things."
 Jahn's reading is here followed. [This is a puzzle as well as a parable; the Seventy give rhamnos, which is not = agnos. It spoils the force of Jotham's caustic satire to adopt this conception of our author.]  1 Kings 19:4.  Genesis 5:29.
