너는 정금으로 등대를 쳐서 만들되 그 밑판과 줄기와 잔과 꽃받침과 꽃을 한 덩이로 연하게 하고
Mishneh Torah, The Chosen Temple
The Menorah, its vessels, the Table, its vessels, the Incense-Altar, and all vessels of the Divine Service may only be made out of metal; they are invalid if made out of wood, bone, stone or glass.
Mishneh Torah, The Chosen Temple
The [sums] work out to twenty-two cups, nine flowers, and eleven knobs, all of which are absolutely necessary. If even one of the forty-two [decorations] are missing, it prevents all of them [from being valid.]
Mishneh Torah, The Chosen Temple
When is the above law [that all the decorations are essential] true? When it is made of gold. However, [if it were made of] other metals, we do not make the cups, knobs, and flowers. Similarly, a golden Menorah must be one talent of gold, including the candles, and hammered out solid while [in the case of Menorahs made of] other metals we do not care about the weight, and it is Kosher even if it is hollow.
