על החוקים לפרטיהם, ספר ד ט׳On the Special Laws, Book IV 9

א׳
1[55] The law holds that all who conform to the sacred constitution laid down by Moses must be exempt from every unreasoning passion and every vice in a higher degree than those who are governed by other laws, and that this particularly applies to those who are appointed to act as judges by lot or election. For it is against all reason that those who claim to dispense justice to others should themselves have offences to answer for. On the contrary it is necessary that they should bear the impress of the operations of nature, as from an original design, and thus imitate them.
ב׳
2[56] Consider the power exerted by fire and snow. Fire warms all it touches but its heat primarily resides in itself, snow its opposite through its own coldness chills other things. So too the judge must be permeated by pure justice if he is to foster with the water of justice those who will come before him, and thus as from a sweet fountain there may issue a stream fit to refresh the lips of those who thirst for true and lawful dealings.
ג׳
3[57] And this will come to pass if a man when he enters upon his duties as judge considers that when he tries a case he is himself on his trial, and with his voting tablet takes also good sense to make him proof against deceit, justice to assign to each according to his deserts, courage to remain unmoved by supplication and lamentation over the punishments of the convicted.
ד׳
4[58] He who studies to possess these virtues will properly be considered a public benefactor. Like a good pilot he steers a prosperous voyage through the storms of business to secure the preservation and security of those who have entrusted their interests to him.
