It’s the effort that counts[1]
ויקם משה את-המשכן ויתן את-אדניו וישם את-קרשיו ויתן את-בריחיו ויקם את-עמודיו
Moshe erected the Mishkan; he placed the sockets and inserted the beams, placed the bars and erected its posts[2]
This week’s parsha includes an accounting of the materials of the Mishkan, the Tabernacle, the manufacturing of the clothing of the Kohanim, and finally the construction of the Mishkan itself. The verse describes how Moshe erected the Mishkan, placing the kerashim, the beams, into their sockets. The Midrash[3] describes the prelude to this: how everyone came to Moshe and said to him that they couldn’t construct the Mishkan; it was too heavy. The beams were massive, and weighed a ton, especially since they were plated in solid gold[4]. Moshe responded by asking them what they expected him to do about that. Moshe was an elderly man in his eighties; they couldn’t reasonably demand that he do it for them. Hashem told Moshe to make an attempt to erect it. Even though his own efforts would have been meaningless, Hashem would do the rest. He made the attempt and was able to erect the beams.
