Midrash sur Chroniques 1 4:9

And this is the thing that thou shalt do unto them (Exod. 29:1). Scripture says elsewhere in reference to this verse: The wise shall inherit honor (Prov. 3:35). Fitting, indeed, is the honor accorded to the wise men who labor in the Torah. The Torah says: Riches and honor are with me; yea, enduring riches and righteousness (Prov. 8:18). You find that though thirty-six generations passed by between Adam and Jabez, the word honor is employed only in reference to Jabez, as it is said: And Jabez was more honorable than his brethren (I Chron. 4:9). Why was he referred to as honorable? Because he was one of the wise men who arranged public assemblies to discuss problems of law, as is said: And the families of scribes that dwelt at Jabez: the Tirathites, the Shimeathites, the Succathites. These are the Kenites that came of Hammath, the father of the house of Rechab (I Chron. 2:55). R. Judah the son of Shalum stated in the name of R. Aibu: Two descendants of Adam were similarly honored, etc.
