God commands that the priests are to light the Menorah in the Mishkan, the place where God will dwell among the Children of Israel.
God says: The priests shall order the flames there, from evening to morning.
God says: the Menorah is to burn always; the priests are to light the Menorah in this way this forever.
*
That is God's introduction to the role of the priests in the Mishkan.
ii
The Mishkan is the dwelling-place of God among Israel.
The priests' first role there is the lighting of the Menorah lights, daily, from evening to morning and forever.
This is the beginnings of how the priests make God dwell among us.
*
God comes to us when we make a schedule out of Light.
