Philo Judaeus De Migratione Abrahami 124

Let us therefore pray that the mind may be in the soul like a pillar in a house, and, in like manner, that the just man may be firmly established in the human race for the relief of all diseases; for while he is in vigorous health, one must not abandon all hope of complete safety, as through the medium of him, I imagine God the Saviour extending his all-healing medicine, that is to say, his propitious and merciful power to his suppliants and worshippers, bids them employ it for the salvation of those who are sick; spreading it like a salve over the wounds of the soul, which folly, and injustice, and all the other multitude of vices, being sharpened up, have ¹ grievously inflicted upon it.
