This week's parsha explains the how the mishkan (tabernacle) and most of its vessels were to be built. The verses detail what materials were to be used, the shapes of the vessels and their dimensions. Here are the verses (Judaica Press translation) about the construction of the menorah:
Exodus Chapter 2531 And you shall make a menorah of pure gold. The menorah shall be made of hammered work; its base and its stem, its goblets, its knobs, and its flowers shall [all] be [one piece] with it.
32 And six branches coming out of its sides: three menorah branches from its one side and three menorah branches from its second side.
33 Three decorated goblets on one branch, a knob and a flower, and three decorated goblets on one branch, a knob and a flower; so for the six branches that come out of the menorah.
34 And on [the stem of] the menorah [shall be] four decorated goblets, its knobs and its flowers.
35 And a knob under the two branches from it, and a knob under the two branches from it, and a knob under the two branches from it; so for the six branches that come out of the menorah.
36 Their knobs and their branches shall [all] be [one piece] with it; all of it [shall be] one hammered mass of pure gold.
37 And you shall make its lamps seven, and he shall kindle its lamps [so that they] shed light toward its face.
38 And its tongs and its scoops [shall be] of pure gold.
39 He shall make it of a talent of pure gold, with all these implements.
40 Now see and make according to their pattern, which you are shown on the mountain.
One question that has puzzled me is why the menorah was required to be made from a single block of gold? Rabbeinu Bachya (1263-1340) provides an answer to this question and explains the meaning of the various parts of the menorah. What follows is a summary of parts of his commentary on verses 31 and 38.
The menorah had seven lamps. The lamps are a hint to the Torah which is called "light," as the verse in Proverbs 6:23: "For the commandment is a lamp and the Torah is light ..."
There were also six branches projecting from the central stem of the menorah. These six branches correspond to the six directions of the world (north, south, east, west, up, down). The world only exists due to the Torah which was given on the sixth of Sivan.
We see from verse 33 that there were three goblets decorating each of the six branches for a total of eighteen goblets. In addition, verse 34 tells us that the central stem was decorated with four more goblets. Hence, there were a total of twenty two goblets, which is a hint to the 22 letters of the Hebrew alphabet which when combined correctly make up the Torah.
From verses 31 and 36 we understand that the menorah must be made from a single piece of gold. Here is a portion of Rashi's commentary on verse 31:
The menorah shall be made of hammered work that it must not be made in sections. Its branches and its lamps should not be made individually and then attached, as is the custom of the smiths called soldering, but it must come entirely from one piece - beaten with a hammer and cut with a tool, and the branches separated on both sides.
None of the other vessels in the mishkan had a requirement that they must be made from a single piece. Why does the menorah have such a requirement? Rabbeinu Bachya shows how the different parts of the menorah are all allusions to the Torah. This is another such allusion: the entire Torah that we have from Hashem is a single Torah. Even though it is composed of different parts such as tanach, midrash, aggadah, mishna and gemara, it is all one Torah.
I would appreciate any comments that you have on this essay.
