Exhort all your household often that all those who serve you shall know to serve God and you, faithfully and painstakingly, and for the will of God to prefer in all things to do your will and pleasure in all things that are not against God.

Command that in no way there be in your household any who make strife, discord or divisions in the hostel, but all shall be of one accord, of one will as of one heart and one soul.

Command that no one be received, or kept to be of your household indoors or without, if one has not reasonable belief of them that they are faithful, discreet, and painstaking in the office for which they are received, and withal honest and of good manners.

The return from cows and sheep in cheese is worth much money every day in the season, without calves and lambs, and without the manure, which all return corn and fruit.

Command that your marshal be careful to be present over the household, and especially in the hall, to keep the household, within doors and without, respectable, without dispute or noise, or bad words.

And be careful of this, that each day at your meals you have two overseers over your household when you sit at meals, and of this be sure, that you shall be very much feared and reverenced.
