Musar su Genesi 6:16

I have already said that man combines within himself elements of all parts of the universe. However, if someone has a face like a human being but acts like an ape, his power extends only within the domain of this physical universe. Afterwards his home would be in the world of the planets since the world of the planets has been assigned by G–d to the various nations, because its origin is also physical. Beneath that world of the planets you have the domain of the קליפות which spawn ghosts and various kinds of evil spirits. All magic, etc. originates in those spheres. The magicians of Egypt derived their power from these spheres. All of these phenomena have their limitations and set measurements. Israel, on the other hand, as a holy nation which cleaves to G–d enjoys an everlasting relationship with G–d and is not subject to limitations in size or function. The standard measure when building is the cubit which consists of 6 handsbreadths. When something approaches the end of its "measure," it is reduced to a single cubit. [We have an example of this description when Noach is instructed to build the slanting roof of the ark in Genesis 6,16: ואל אמה תכלנה מלמעלה Ed.] Pharaoh's body is described as only one cubit tall, since it symbolised a human being whose only place is this physical world. The physical universe is perceived as progressively reducing in size until finally it is only a single cubit high. Our sages have described the physical universe as comprising a distance of 500 years' walk. A man is presumed to walk an average of 10 Parsa-ot daily. [45 km] daily. Ed.] Every one of those 10 Parsa-ot comprises 4 Milin, and every one of those Milin equals 2000 cubits. A cubit is presumed to be the length of an average person's step. Just as there are 6 handsbreadths in a cubit, so there were 6 days during the course of which G–d created the physical universe. This universe is supposed to last for 6000 years. When Avital the scribe referred to the beard of Pharoh as being one cubit long, he referred to the world of the planets, since their size will also experience reduction to a single cubit, albeit 500 years' walk away from earth.

The third and highest level of accommodation in the ark was reserved for אדם, man, who is the יסוד העולם, foundation of the universe, seeing the image of Jacob is engraved in G–d's throne. Concerning all three levels of the ark, we apply the verse בראש מגדול הוא שם ה', בו ירוץ צדיק ונשגב of Proverbs, that G–d is above those levels.
