Apostolic Constitutions, Book VII 4
1You shall not speak evil; for says He, Love not to speak evil, lest you beest taken away. Nor shall you be mindful of injuries; for the ways of those that remember injuries are unto death. You shall not be double-minded nor double-tongued; for a man's own lips are a strong snare to him, and a talkative person shall not be prospered upon earth. Your words shall not be vain; for you shall give an account of every idle word. You shall not tell lies: for says He, You shall destroy all those that speak lies. You shall not be covetous nor rapacious: for says He, Woe to him that is covetous towards his neighbour with an evil covetousness.
