90 For I own that I am too weak for this warfare, and therefore turned my back, hiding my face in the rout, and sat solitary, because I was filled with bitterness and sought to be silent, understanding that it is an evil time, that the beloved had kicked, that we had become backsliding children, who are the luxuriant vine, the true vine, all fruitful, all beautiful, springing up splendidly with showers from on high. For the diadem of beauty, the signet of glory, the crown of magnificence has been changed for me into shame; and if anyone, in face of these things, is daring and courageous, he has my blessing on his daring and courage.
