Sanctify unto me all the firstborn, whatsoever opens the womb among the children of Israel, both of man and of beast: it is mine.
All Commentaries on Exodus 13:2 Go To Exodus 13
Tertullian of Carthage
AD 220
For who is really holy but the Son of God? Who properly opened the womb but he who opened a closed one? But it is marriage which opens the womb in all cases. The Virgin’s womb, therefore, was especially opened, because it was especially closed. –.
