(Bamidbar 27:20) "And you shall place (some) of your glory (i.e., shining of countenance) upon him": and not all of your glory — whence we derive "The face of Moses was like the face of the sun; the face of Joshua was like the face of the moon."
(Bamidbar 27:21) "And before Elazar the Cohein shall he (Joshua) stand": Joshua had recourse to Elazar, and Elazar, to Joshua. "And he (Joshua) shall inquire of him (Elazar)": I might think, (that the inquiry was) "between him and himself"; it is, therefore, written "as to the judgment of the urim." I might then think, (that he inquired) in full voice. It is, therefore, written "and he shall inquire of him," (connoting in subdued voice). How so? He stood and moved his lips, and the high-priest answered his inquiries.
