His Oath
Also he would never use any other oath to confirm his own truthful speech than the uttering of these words: ‘Forsothe and forsothe,’ to certify those to whom he spoke of what he said. So also he restrained many both gentle and simple from hard swearing either by mild admonition or harsh reproof; for a swearer was his abomination.
When he heard a great lord who was his chamberlain suddenly break out and swear bitterly, he sternly rebuked him, saying: ‘Alas! you, that are lord of a great household, when you utter oaths like this contrary to God’s commandment, give a most evil example to your servants and those that are under you, for you provoke them to do the like.’
