2. Mose 18:25

The judges chosen were arranged as chiefs (שׂרים) over thousands, hundreds, fifties, and tens, after the analogy of the military organization of the people on their march (Num 31:14), in such a manner, however, that this arrangement was linked on to the natural division of the people into tribes, families, etc. (see my Archologie, 140). For it is evident that the decimal division was not made in an arbitrary manner according to the number of heads, from the fact that, on the one hand, the judges were chosen from the heads of their tribes and according to their tribes (Deu 1:13); and on the other hand, the larger divisions of the tribes, viz., the families (mishpachoth), were also called thousands (Num 1:15; Num 10:4; Jos 22:14, etc.), just because the number of their heads of families would generally average about a thousand; so that in all probability the hundreds, fifties, and tens denote smaller divisions of the nation, in which there were about this number of fathers. Thus in Arabic, for example, "the ten" is a term used to signify a family (cf. Hengstenberg, Dissertations v. ii. 343, and my Arch. 149). The difference between the harder or greater matters and the smaller matters consisted in this: questions which there was not definite law to decide were great or hard; whereas, on the other hand, those which could easily be decided from existing laws or general principles of equity were simple or small. (Vide Joh. Selden de Synedriis i. c. 16, in my Arch. 149, Not. 3, where the different views are discussed respecting the relative positions and competency of the various judges, about which there is no precise information given in the law.) So far as the total number of judges is concerned, all that can be affirmed with certainty is, that the estimated number of 600…

This chapter is concerning Moses himself, and the affairs of his own family. I. Jethro his father-in-law brings to him his wife and children (Exo 18:1-6). II. Moses entertains his father-in-law with great respect (Exo 18:7), with good discourse (Exo 18:8-11), with a sacrifice and a feast (Exo 18:12). III. Jethro advises him about the management of his business as a judge in Israel, to take inferior judges in to his assistance (Exo 18:13-23), and Moses, after some time, takes his counsel (Exo 18:24-26), and so they part (Exo 18:27).
