On this account Moses, in his passages of exhortation, says, "If thou goest forth to battle against thy enemies, and if thou seest numbers of horses, and riders, and people, be not afraid, because the Lord thy God is with thee." Deut. xx. 1. For we must neglect anger and desire, and, in short, all the passions, and indeed the whole company of reasonings, which are mounted upon each of the passions as upon horses, even if they believe that they can exert irresistible strength; at least, all those must do so who have the power of the great King holding a shield over them, and in every place, and at every time, fighting in their defence.
