Duties of masters and servants
You masters, do not treat your servants with haughtiness, but imitate patient Job, who declares, “I did not despise the cause of my man-servant, or of my maid-servant, when they contended with me. For what in that case shall I do when the Lord makes an inquisition regarding me?” And you know what follows. You servants, do not provoke your masters to anger in anything, lest you become the authors of incurable mischiefs to yourselves.
