One might think that he went but did not do so. It is, therefore, written (Judges 1:16) "And the children of Keni, the father-in-law of Moses, went up from the city of date-palms," and (Ibid.) "and they went and settled with the people," "the people" signifying "wisdom," (in this instance, Torah study), viz. (Iyyov 12:2) "Truly you are a people, but will wisdom die with you?" Read if not "tamuth" ("die"), but "tumath" ("put to death"). So long as a sage lives, his wisdom endures. When he dies, his wisdom is lost with him.
