Gálatas 4

Now the son by the servant-woman has his birth after the flesh; but the son by the free woman has his birth through the undertaking of God.

Mas el de la sierva nació según la carne; pero el de la libre nació por la promesa.

But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.

However, the son by the servant was born according to the flesh, but the son by the free woman was born through promise.
