And the LORD said unto Noah,
Come you and all your house into the ark; for you have I seen righteous before me in this generation.
All Commentaries on Genesis 7:1 Go To Genesis 7
Augustine of Hippo
AD 430
By this prefiguration it is prophesied that in the church there will be the impure by reason of tolerance, not because of corruption of doctrine or dissolution of discipline. Furthermore, the unclean animals did not break their way into the ark through any part of the structure, but because the ark was an integral whole, they entered by the one and only entrance that the architect had made.
