Halakhah к Шофтим 9:36

I have written from the roots of the commandment in the Order of Mishpatim on the negative commandment of the chieftain (Sefer HaChinukh 71). And there I wrote at length about the benefit that is found for a people in there being one person upon them as the head and as the officer; as the order of the people will not be preserved without this. And behold, you see in the books of the Prophets that it comes as a curse when many people are the head in one place - and as it is written (see the book of Judges 9).
