See here, 1. What ought to be the care of a servant, the meanest that is sent on an errand and entrusted with any business, much more the greatest, the agent and ambassador of a prince; he ought to be faithful to him that sends him, and to see to it that he do not, by mistake or with design, falsify his trust, and that he be in nothing that lies in his power wanting to his master's interest.
Those that act as factors, by commission, ought to act as carefully as for themselves. 2. How much this will be the satisfaction of the master; it will refresh his soul as much as ever the cold of snow (which is hot countries they preserve by art all the year round) refreshed the labourers in the harvest, that bore the burden and heat of the day.
The more important the affair was, and the more fear of its miscarrying, the more acceptable is the messenger, if he have managed it successfully and well. A faithful minister, Christ's messenger, should be thus acceptable to us (Job 33:23); however, he will be a sweet savour to God, 2 Corinthians 2:15.
