Cicero (on the Stoics), On Duties 3.23

But this principle is established not by Nature's laws alone (that is, by the common rules of equity), but also by the statutes of particular communities, in accordance with which in individual states the public interests are maintained. In all these it is with one accord ordained that no man shall be allowed for the sake of his own advantage to injure his neighbour. For it is to this that the laws have regard; this is their intent, that the bonds of union between citizens should not be impaired; and any attempt to destroy these bonds is repressed by the penalty of death, exile, imprisonment, or fine. Again, this principle follows much more effectually directly from the Reason which is in Nature, which is the law of gods and men. If anyone will hearken to that voice (and all will hearken to it who wish to live in accord with Nature's laws), he will never be guilty of coveting anything that is his neighbour's or of appropriating to himself what he has taken from his neighbour.
