Blessed is the mind of that man who, overstepping the bounds of species and race, deserves to hear what was said to Moses when he stood apart from his people: "Stand here with me."―St Ambrose

The intention of the law was that in everything they should look toward what is real. They should not make up things which are different from reality or misrepresent what is truly male or what is really female, or the nature of beasts or the species of birds or creeping things, or fishes―Origen

And here this other fact will not appear to be without significance, that it is Moses who hears from God all that is written down in the law of Leviticus, whereas in Deuteronomy it is the people who are represented as listening to Moses and learning from him what they could not hear from God. This indeed is why it is called Deuteronomy, meaning the second law. A fact which some will think points to this [is] that when the first law given through Moses came to an end, a second legislation was apparently composed, and this was specially delivered by Moses to his successor Joshua.3 And Joshua is certainly believed to be a figure of our Savior, by whose second law, that is, by the precepts of the Gospels, all things are brought to perfection―Origen
