כִּכָּ֛ר זָהָ֥ב טָה֖וֹר יַעֲשֶׂ֣ה אֹתָ֑הּ אֵ֥ת כָּל־הַכֵּלִ֖ים הָאֵֽלֶּה׃
등대와 이 모든 기구를 정금 한 달란트로 만들되
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.
