11 I pass by in silence what is still more ineffable, of which God is witness, and those of the faithful handmaidens to whom she has confided such things. That which concerns myself is perhaps undeserving of mention, since I have proved unworthy of the hope cherished in regard to me: yet it was on her part a great undertaking to promise me to God before my birth, with no fear of the future, and to dedicate me immediately after I was born. Through God's goodness has it been that she has not utterly failed in her prayer, and that the auspicious sacrifice was not rejected.
Some of these things were already in existence, others were in the future, growing up by means of gradual additions. And as the sun which most pleasantly casts its morning rays, becomes at midday hotter and more brilliant, so also did she, who from the first gave no slight evidence of piety, shine forth at last with fuller light. Then indeed he, who had established her in his house, had at home no slight spur to piety, possessed, by her origin and descent, of the love of God and Christ, and having received virtue as her patrimony; not, as he had been, cut out of the wild olive and grafted into the good olive, yet unable to bear, in the excess of her faith, to be unequally yoked; for, though surpassing all others in endurance and fortitude, she could not brook this, the being but half united to God, because of the estrangement of him who was a part of herself, and the failure to add to the bodily union, a close connection in the spirit: on this account, she fell before God night and day, entreating for the salvation of her head with many fastings and tears, and assiduously devoting herself to her husband, and influencing him in many ways, by means of reproaches, admonitions, attentions, estrangements, and above all by her own character with its fervour for piety, by which the soul is specially prevailed upon and softened, and willingly submits to virtuous pressure. The drop of water constantly striking the rock was destined to hollow it, and at length attain its longing, as the sequel shows.
