6. Because, therefore, for the security of particular men, and, by consequence, for the common peace, it is necessary that the right of using the sword for punishment be transferred to some man or council; that man or council is necessarily understood by right to have the supreme power in the city. For he that by right punisheth at his own discretion, by right compels all men to all things which he himself wills; than which a greater command cannot be imagined. [Sidenote: That the sword of war belongs to him also.] 7. But in vain do they worship peace at home, who cannot defend themselves against foreigners; neither is it possible for them to protect themselves against foreigners, whose forces are not united. And therefore it is necessary for the preservation of particulars, that there be some one council or one man, who hath the right to arm, to gather together, to unite so many citizens, in all dangers and on all occasions, as shall be needful for common defence against the certain number and strength of the enemy; and again, as often as he shall find it expedient, to make peace with them. We must understand, therefore, that particular citizens have conveyed their whole right of war and peace unto some one man or council; and that this right, which we may call _the sword of war_, belongs to the same man or council, to whom the sword of justice belongs. For no man can by right compel citizens to take up arms and be at the expenses of war, but he who by right can punish him who doth not obey. Both swords therefore, as well this of war as that of justice, even by the constitution itself of a city and essentially do belong to the chief command. [Sidenote: The power of judicature belongs to him.] 8. But because the right of the sword, is nothing else but to have power by right to use the sword at his own will, it follows, that the judgment of its right use pertains to the same party; for if the power of judging were in one, and the power of executing in another, nothing would be done. For in vain would he give judgment, who could not execute his commands; or, if he executed them by the power of another, he himself is not said to have the power of the sword, but that other, to whom he is only an officer. All judgment therefore, in a city, belongs to him who hath the swords; that is, to him who hath the supreme authority. [Sidenote: The legislative power is his also.]
