דַּבֵּר֙ אֶֽל־אַהֲרֹ֔ן וְאָמַרְתָּ֖ אֵלָ֑יו בְּהַעֲלֹֽתְךָ֙ אֶת־הַנֵּרֹ֔ת אֶל־מוּל֙ פְּנֵ֣י הַמְּנוֹרָ֔ה יָאִ֖ירוּ שִׁבְעַ֥ת הַנֵּרֽוֹת׃
“Berbicaralah kepada Harun dan katakanlah kepadanya: Apabila engkau menyalakan pelita-pelita itu, ketujuh pelita itu harus memancarkan cahaya ke arah depan kandil itu.”
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.
