“Grant to them, Lord, health, peace, concord, and stability, so that they may exercise without offense the sovereignty that you have given them.

Direct, Lord, their counsel, following what is pleasing and acceptable in your sight, so that by exercising with devotion and in peace and gentleness the power that you have given to them, they may find favor with you.”
