You shall not plow with an ox and a donkey together.
All Commentaries on Deuteronomy 22:10 Go To Deuteronomy 22
Clement Of Alexandria
There it is perhaps guessing at the disparity between the animals. It is at the same time showing clearly that we must not wrong any of those from other races by bringing them under the same yoke when we have nothing against them apart from their foreignness, for which they are not responsible, which is not an immoral trait and does not spring from one. It is my view that this is an allegory, meaning that we should not share the cultivation of the Logos on equal terms between pure and impure, faithful and faithless, as the ox is accounted a clean animal and the donkey unclean.
