My beloved son, delight of my heart, hope of your posterity, I pray, I command, that at very time and in everything, strengthened by your devotion to me, you may show favor not only to relations and kin, or to the most eminent, be they leaders or rich men or neighbors or fellow-countrymen, but also to foreigners and to all who come to you. By fulfilling your duty in this way you will reach the highest state of happiness…

The guests and newcomers are of so much service that they may rightly be ranked sixth among the royal dignities. As in the beginning the Roman Empire was in this manner formed, so were the Roman Emperors exalted and made honorable, so that many noble and wise men joined them in a better and better realm. For as the guests arrive from different parts and provinces, so they bring with them different tongues and customs, different examples and weapons, and all this adorns the country and enhances the splendor of the court while deterring foreigners from triumphalist contempt. For a country of one single language and one set of customs is weak and vulnerable. Therefore I enjoin on you, my son, to protect newcomers benevolently and to hold them in high esteem so that they should stay with your rather than dwell elsewhere.
