“Magsalita ka kay Aaron at sabihin mo sa kanya: Kapag sinindihan mo ang mga ilawan, ang pitong ilawan ay magbibigay-liwanag patungo sa harap ng kandelero.”
Mishneh Torah, The Chosen Temple
The six lamps which are attached to the six branches all point towards the middle lamp which is on the stem of the Menorah, and this middle lamp points towards the Holy of Holies and is called the "Western Lamp."
Mishneh Torah, The Chosen Temple
There was a stone in front of the Menorah with three steps [cut] in it on which the High Priest would stand and set up the lamps and he would rest the tweezers and oil vessels etc. on it when setting them up.
