Shemot 26:13

והאמה מזה והאמה מזה AND A CUBIT ON THE ONE SIDE AND A CUBIT ON THE OTHER SIDE — i. e. on the north and on the south, בעדף בארך יריעת האהל OF THE SURPLUS OF THE LENGTH OF THE CURTAINS OF THE TABERNACLE — i. e. which were in excess over the curtains of “the Tabernacle” (the woollen ones) by two cubits, יהיה מרוח על צדי המשכן SHALL HANG OVER THE SIDES OF THE TABERNACLE — on the north and on the south as I have explained above. The Torah here teaches you a rule of life — that a man should take care of his artistic objects (this the Torah does by commanding that the beautiful lower curtains should be protected by coarse upper ones) (Yalkut Shimoni on Torah 422).

וְהָאַמָּ֨ה מִזֶּ֜ה וְהָאַמָּ֤ה מִזֶּה֙ בָּעֹדֵ֔ף בְּאֹ֖רֶךְ יְרִיעֹ֣ת הָאֹ֑הֶל יִהְיֶ֨ה סָר֜וּחַ עַל־צִדֵּ֧י הַמִּשְׁכָּ֛ן מִזֶּ֥ה וּמִזֶּ֖ה לְכַסֹּתֽוֹ׃

And a cubit on the one side, and a cubit on the other side, of that which remains in the length of the curtains of the tent, shall hang over the sides of the tabernacle on this side and on that side, to cover it.
