Moses distinguished Joshua not because God had ordered him to do so, but because he was sincerely glad to pass his dignity on to him, just as a father is glad to leave his possessions to his son. So, too, whereas God had bidden Moses to lay only one hand upon Joshua's head and in this way put his honor upon him, Moses fulfilled God's command by laying both his hands upon Joshua, and by this action bestowed upon him not only insight and understanding, but also a radiant countenance like that of Moses, from whose face issued rays like those of the sun.
In giving all these qualities to Joshua, Moses lost nothing. Moses' wisdom was like a torch, whereas Joshua's may be compared to a candle only, and just as a torch loses none of its intensity if a candle is lighted therefrom, so little was Moses' wisdom diminished by the wisdom he gave to Joshua. The rays, too, that emanated from Joshua's countenance were weaker than those from Moses', and not until the crossing of the Jordan did they attain their full intensity, so that upon beholding them, "the people feared him as they feared Moses."
