תּלמוד אויף שמות 26:16

Now what was the height of the Tabernacle? Ten cubits, as it is written, "Ten cubits shall be the length of a board" (Exodus 26:16). How much is this? Sixty handbreadths. How much is a third? Twenty handbreadths. Deduct the ten of the ark and the ark-cover, and ten handbreadths remain; and it is written, "And the cherubim shall spread out their wings on high, covering the ark-cover with their wings" (Exodus 25:20). [From which we see that] that the Merciful One calls [the wings that were stretched] above a height of ten handbreadths a ‘covering."

Rabbi Yochanan says The Holy One, blessed be he, does not rest his divine presence except on a person who is might, wealthy, wise, and humble. And all of these [we learn] from Moses.
