על החוקים לפרטיהם, ספר ד ל״גOn the Special Laws, Book IV 33

א׳
1[170] The person who has been judged worthy to fill the highest and most important office should choose lieutenants to share with him the duties of governing, giving judgement, and managing all the other matters which concern the public welfare. For a single person even though possessed of unique strength both in body and soul would not be capable of coping with the magnitude and multitude of affairs, be he ever so zealous, but would collapse under their force as they pour in upon him daily from different sides, unless he had helpers all of the best chosen for their good sense, ability, justice and godliness, and because they not only keep clear of arrogance but hate it as a thing pernicious and utterly evil.
ב׳
2[171] In such persons the man of high excellence burdened with state affairs will find assistants and supporters well fitted to join in relieving him and to lighten his task. Further, since the questions which arise are sometimes greater and sometimes less, to prevent his wearing himself out in petty matters he will do rightly in entrusting the smaller to his subordinates, while the greater he will be bound to scrutinize himself with the utmost care.
ג׳
3[172] And great questions must not be understood, as some think, to mean cases where both the disputants are distinguished or rich or men in high office but rather where the commoner or the poor or the obscure are disputing with others more powerful, and where their one hope of escaping a fatal disaster lies in the judge.
ד׳
4[173] Both these statements may be justified by clear examples to be found in the sacred laws, examples which we do well to copy. For there was a time when Moses himself arbitrated questions of justice, labouring from morning till night, but afterwards when his father-in-law arrived and observed the vast burden of affairs which oppressed him through the perpetual flood of persons who had questions to settle, he gave the excellent advice that Moses should choose delegates to judge the smaller matters and keep himself in reserve for the greater and thus allow himself time to rest.
ה׳
5[174] Moses listened to this truly valuable advice and chose out of the multitude the men of highest repute whom he appointed as subordinate governors and also as judges, bidding them refer the more important suits to himself.
ו׳
6[175] A record of the course thus taken is included in the sacred books as a lesson to each generation of rulers, first that they should not, under the impression that they are capable of surveying everything, reject the help of councillors which Moses the supremely wise and beloved of God did not reject; next that they should choose officers to act as second and third to themselves and so take care that they did not by wearing themselves out over petty matters neglect the more vital. For human nature cannot possibly reach everything.
