Fidelity to one’s lord consists in not conferring on someone else the honor of preeminence; and on this score there is the first precept, when it says, “You shall not have strange gods.” Reverence to one’s lord requires that nothing injurious be done to him; and on this score there is the second precept, i.e., “You shall not take the name of the Lord your God in vain.” Service is owed to a lord in repayment for the benefits his subjects receive from him; and here the relevant precept is the third, which has to do with the sanctification of the Sabbath in remembrance of the creation of things.
Il rispetto verso un padrone richiede che non si commetta niente di ingiurioso verso di lui. E pertanto il secondo precetto dice «Non nominerai il nome di Dio invano».
