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.
