Halakhah su Isaia 54:12

And you already knew that the words of our rabbis follow the Torah’s means of expression, and so in the Torah there are permitted and prohibited foods: this you shall eat; this you shall not eat, and it is written, “from their flesh you shall not eat.”²⁷Lev 11:8. You wouldn’t say that this is an allegory – God forbid! – but it’s the actual literal meaning. And so they went on to say The Holy One, blessed be He, will in time to come make a sukkah for the righteous from the skin of Leviathan; for it is said: “Can you fill sukkot with his skin?”²⁸Job 40:31. Sukkot here is spelled with a sin, not a samekh as in sukkah meaning “tent,” and means “darts.” Thus, the meaning of the verse in context is “Can you fill his skin with darts?” If a man is worthy, a sukkah is made for him; if he is not worthy, a shadow [tzel] is made for him, for it is said: “And his head with a fish covering [bi-tziltzel].”²⁹Job 30:41. R. Bahya following the Talmud takes the two parts of this verse in Job as contrasting: the first part hints at the reward of the worthy, the second part to the punishment of the unworthy – “shade.” After this he skips a few lines of Talmud that expand on this theme of the worthy and unworthy’s “rewards.” The rest [of Leviathan] will be spread by the Holy One, blessed be He, upon the walls of Jerusalem, and its splendor will shine from one end of the world to the other; as it is said: “And nations shall walk by Your light.”³⁰Is 60:3, in b. Baba Batra 75a.

And in connection to this you will also find it plainly stated in Perek Helek³⁴B. Sanhedrin 100a, a well-known passage from the Talmud describing the world to come. that in time to come the human height [komot] will return to two hundred cubits, and they also taught this in a midrash likewise in Perek Sefinah:³⁵B. Baba Batra 75a. “I will lead you komamiyut,”³⁶Lev 26:13, literally, “I will make you walk erect” (JSB), but the midrash plays on the similarity between komamiyut “erect” and komot – “height.” R. Meir says: [it means] two hundred cubits – twice the height of Adam. R. Judah says: A hundred cubits; corresponding to the [height of the] temple and its walls. For it is said: ‘carved after the fashion of the Temple.³⁷Ps 144:22. But insofar as it said,³⁸B. Baba Batra, ibid. The Holy One, Blessed be He, will in time to come bring precious stones and pearls…and will cut out from them [openings] ten by twenty cubits, and will set them up in the gates of Jerusalem, as it is said, “and your gates of stones of carbuncle,”³⁹Is 54:12. it seems from this that the height will be no more than twenty cubits. So therefore it must be said that the gates of the houses are not being spoken about, for how could they enter them at that height?! But rather, it’s certainly the gates of the windows that are being spoken about. And you already knew that parashat “Im Behukotai” is a promise of what will happen in the future, for what it says there never existed in the two Temples, neither in the First nor the Second Temple. For what is destined in the Torah through its promises is not al shlemut, but will happen in time to come after the ancient sin has been atoned for, which has never occurred at any time, and this is what our sages z”l taught in a midrash:⁴⁰B. M.K. 16b. When David went out to war he killed eight hundred at one time, but was sorry for the two hundred [he would have killed], to fulfill what has been said, “How could one have routed a thousand?”⁴¹Dt 32:32, from the future promises enumerated in Deuteronomy. A voice from heaven went out and said, “Were it not for the matter of Uriah the Hittite.”⁴²1 Kings 15:5, and see the story in 2 Samuel chapters 11-12. King David fell in love with Uriah’s wife Bathsheba, and so sent Uriah off to the front lines of battle to be killed so that he could marry her.
