Kandil itu beserta semua perkakas ini harus dibuat dari satu talenta emas murni.
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.
