וַיַּ֥עַשׂ אֶת־הַקְּרָשִׁ֖ים לַמִּשְׁכָּ֑ן עֲצֵ֥י שִׁטִּ֖ים עֹמְדִֽים׃
E fece le assi del tabernacolo, di legni d’acacia, in piedi [segate per lo lungo].
Midrash Tanchuma
And he made the boards for the tabernacle of acacia-wood (Exod. 36:20). R. Tahlifa of Caesarea said: The Holy One, blessed be He, taught man correct behavior. If a man desired to build a house with the wood of a fruit-producing tree, one should say to him: Since the Holy One, blessed be He, to whom everything belongs, prohibited the use of the wood of a fruit-bearing tree in building the Tabernacle, how much more so are you prohibited from doing that.
Midrash Tanchuma
What is suggested by the word mishkan (“Tabernacle”)? If Israel is worthy (of punishment), the Tabernacle would be seized as a pledge (mashkon) for them. Moses said: Master of the Universe, when there is neither a Tabernacle nor a Temple, what will serve as a pledge for them? He answered: I shall take the righteous from among them, and they will be their pledge. Hence it says: And he that hath slain all that were pleasant to the eye (Lam. 2:4). These are the righteous. Therefore it is written: And he made the boards for the Tabernacle of acacia-wood (Exod. 36:20).
