My dear successor, if you have loved me during my life, so after my death you can show your love to me by making the King’s Regiment your regiment and leaving it with its present pay and distinguish it for my sake; secondly, continue to enlarge the town of Potsdam and give it the name of Wilhelmsstadt, for which God will give it His blessing.
Meanwhile I commend my soul to God and herewith give you once again my paternal blessing and wish you to keep God before your eyes and to rule your lands justly and in fear of God, and may you always have loyal servants and obedient subjects and a strong arm and a victorious army against all your enemies, and I pray that you, my dear successor, and those that come after you, may prosper as Kings and Electors to the end of the world, and that your provinces may prosper from hour to hour. May Almighty God help you to this through Jesus Christ!
Your true father, till death
Potsdam, the 17th February, 1722
