Another thing necessary for the maintaining of peace, is the due execution of justice, which consisteth principally in the right performance of their duties, which are the magistrates, ordained for the same by and under the authority of the sovereign power, which being private men in respect of the sovereign, and consequently such as may have private ends, whereby they may be corrupted with gifts, or intercession of friends, ought to be kept in awe by an higher power, lest people, grieved by their injustice, should take upon them to make their own revenges, to the disturbance of the common peace; which can by no way be avoided in the principal and immediate magistrates, without the judicature of the sovereign himself, or some extraordinary power delegated by him.

And not only so, but also to ordain severe punishments for such, as shall by reprehension of public actions, affect popularity and applause amongst the multitude, by which they may be enabled to have a faction in the commonwealth at their devotion.
