Leaning, learning and light

‘And the Lord said to Moses, “Take for yourself Joshua the son of Nun, an individual who has spirit within him, and lay [or lean] your hand upon him; Stand him up before Elazar the Priest and before the entire congregation; and command him before their eyes. And give of your glory upon him in order that the entire congregation of the children of Israel may obey him”’ (Numbers 27:18-20)
