Because the name Jacob means "a supplanter," but the name Israel signifies "the man who sees God." Now it is the employment of a supplanter, who practises virtue, to move, and disturb, and upset the foundations of passion on which it is established, and whatever there is of any strength which is founded on them. But these things are not brought about without a struggle or without severe labour; but only when any one, having gone through all the labours of prudence, then proceeds to practise himself in the exercises of the soul and to wrestle against the reasonings which are hostile to it, and which seek to torment it; but it is the part of him who sees God not to depart from the sacred contest without the crown of victory, but rather to carry off the prize of triumph.
