When we lay bare the hidden meaning of the history, scripture is seen to teach that the birth which distresses the tyrant is the beginning of the virtuous life. I am speaking of the kind of birth in which free will serves as the midwife, delivering the child amid great pain. For no one causes grief to his antagonist unless he exhibits in himself those marks which give proof of his victory over the other.

St. Gregory of Nyssa, The Life of Moses.
