Philo Judaeus Quod Deus Sit Immutabilis 66

[66] For what man in his senses would say to a patient under his care, "My good man, you shall have the knife applied to you, and cautery, and your limbs shall be amputated," even if such things were absolutely necessary to be endured? No man on earth would say so. For if he did, his patient would sink in his heart before the operations could be performed, and so receiving another disease in his soul, more grievous than that already existing in his body, he would resolutely renounce the cure; but if, on the other hand, through the deceit of the physician he is led to form a contrary expectation, he will submit to everything with a patient spirit, even though the means of his salvation may may be most painful.
