Philo Judaeus De Mutatione Nominum 230

[230] And it is something like this that Esau seems to have said to his father, "Have you not one blessing for me, O my father? Bless me, bless me, also, O my father!" ¹ For different blessings have been set apart for different persons, perfect blessings for the perfect, and moderate blessings for the imperfect. As is the case also with bodies; for there are different exercises appropriate to those which are in health, and to those which are sick. And also different regimens of food, and different systems of living, and not the same. But some things are suitable to the one kind that they may not become at all diseased; and other things are good for the other sort, that they may be changed and rendered more healthy.
