The Torah portion begins with the command pertaining to kindling the candelabrum in the Tabernacle. The Sages relate the difficulty in crafting the candelabrum, until ultimately it was formed on its own, in a miraculous manner.
“This is the craftsmanship of the candelabrum: Hammered gold [miksha]” (Numbers 8:4). In other words, the verse means to allude to how difficult it was for Moses to craft it. Moses exerted much effort trying to understand how to craft it. When he had difficulty, the Holy One, Blessed be He, said to Moses: Take a talent of gold and cast it into the fire and remove it, and it will craft itself, as it is stated: “Its base and its shaft; its cups, its knobs and its flowers, were from it” (Exodus 37:17). The term “from it” indicates that Moses strikes with the hammer, and it is crafted from itself. Therefore, the verse states: “The candelabrum shall be made [te’aseh] hammered” (Exodus 25:31), written with [the Hebrew letter] yod. “Shall make [ta’aseh]” is not written, as if to say that it will be crafted on its own. Moses took the talent of gold and cast it into the fire. Moses said: Master of the Universe! The talent is in the fire. Just as You want, so shall You do. Immediately, the candelabrum emerged, crafted in accordance with its specifications. (BemidbarRabba 15)
