De Decalogo

The third, that which forbids stealing, is the one under cover of which are enacted all the regulations which have been laid down, respecting the repudiation of debts, and those who deny what has been deposited with them, and who form unhallowed partnerships, and indulge in shameless acts of rapine, and, in short, in any kind of covetousness by which some persons are induced, either openly or secretly to appropriate the possessions of others.

The fourth, that which is concerning the duty of not bearing false witness, is one under which many other prohibitions are conveyed, such as that of not deceiving, of not bringing false accusations, of not co-operating with those who are committing sin, of not making a pretence of good faith a cloak for faithlessness; for all which objects suitable laws have been enacted.
