9-18. I spake unto you at that time, saying, I am not able to bear you myself alone--a little before their arrival in Horeb. Moses addresses that new generation as the representatives of their fathers, in whose sight and hearing all the transactions he recounts took place. A reference is here made to the suggestion of Jethro (Ex 18:18). In noticing his practical adoption of a plan by which the administration of justice was committed to a select number of subordinate officers, Moses, by a beautiful allusion to the patriarchal blessing, ascribed the necessity of that memorable change in the government to the vast increase of the population.
