Kabbalah su Isaia 26:78

"And Elohim spoke to Moses and said to him, 'I am Hashem and I appeared to Abraham, to Isaac, and to Jacob, by the name of El Shadai...'" (Shemot 6:2-3). Rabbi Abba opened the discussion saying, "Trust in Hashem forever (Heb. עֲדֵי עַד), for Yah Hashem is an everlasting rock" (Isaiah 26:4). "Trust in Hashem" means that all the people of the world have to strengthen themselves in the Holy One, blessed be He, and trust in Him.

Therefore "Trust in Hashem forever" (Isaiah 26:4). For from there up, the place is covered and hidden, as none can conceive it. It is a place from which the worlds emerge and are formed. This is the meaning of, "For Yah Hashem is an everlasting rock." This place is hidden and concealed. Therefore, "Trust in Hashem forever (Heb. adei ad)," that up to here, everyone is permitted to observe. From here and further no one is permitted to observe because it is concealed from everyone. And what is Yah, Yud Hei Vav Hei, whence all the worlds were formed, and no one is able to understand that place, in order to conceive anything.

What is the reason? Since the world endures by His Holy Name. This is the meaning of, "For Yah Hashem is an everlasting (lit. 'worlds') rock (Heb. tzur)" (Isaiah 26:4), the former (Heb. צַיָּיר) of worlds. For by two letters were the worlds created, this world and the World to Come. This world was created with Judgment and is maintained on Judgment. This is the meaning of, "In the beginning Elohim created" (Beresheet 1:1). The reason is so that people would conduct themselves according to judgment (law) and would not digress from the path.

[My soul weeps] in secret places for your pride (Jer. 13:17) and is faint all the day (Lam. 1:13). The altar of the wicked is an abomination (Prov. 21:27). Yet despite this, many waters cannot quench love (Song 8:7), for upright are the ways of the Lord (Hos. 14:10). He will judge the poor of the people (Ps. 72:4), He will establish peace (Isa. 26:12). When He speaks He will overcome the mighty (Eccles. 10:10) for His people and His pious ones.

For from the quarrelsome words of the immature grain, a thorn has spread among the brethren and rebellion like the sin of witchcraft (I Sam. 15:23). When the time comes she raises her wings on high (Job 39:18). God know the days of the perfect (Ps. 37:18) and the way of the righteous (Ps. 1:6), and raises up from the dust (Ps. 113:7) and the far distant sea (Ps. 65:6) all the souls of the house of Jacob (Gen. 46:27). They all eagerly desire to hear the word of God and the ancient records (I Chron. 4:22). However, [until] now they have not seen the clear light of [Him who dwells] in the skies. For from the top of the Rocks I see Him (Num. 23:9), and among those who turn the many to righteousness (Dan. 12:3) I behold Him. Grace is poured upon their lips (Ps. 45:3) like roses (Song 5:13). Their waters are more sure than the garden spring, a well of living waters (Song 4:15). Like doves [going] to their cotes (Isa. 60:8) they have drunk spices. They call to God, and He answers them (Ps. 99:6). This one says, I am the Lord’s (Isa. 44:5), answer me with broad spaces (Ps. 118:5), for my heart does not rest at night (Eccles. 2;23), nor does my spirit within me (Isa. 26:9). This one writes with his hand to the Lord (Isa. 44:5) from that which had preceded him [at] Sinai, and on the skins of kid goats (Gen. 27:16) they set up their signs (Ps. 74:4) which they wrote to instruct them for their generations, an eternal covenant (Exod. 31:16).

"And I will make you swear by Hashem, the Elohim of heaven" (Beresheet 24:3). "And I will make you swear." What is the meaning of, "I will make you swear"? He will be clothed in the secret of the seven Supernal Lights, they are the secret of supernal perfection. "That you shall not take a wife," refers to the body underneath the ground, which now rises from the dust. All those who were buried and deserved to be interred in the land of Yisrael shall be the first to rise to life, as has been explained in relation to the verse, "The dead men of your people shall live" (Isaiah 26:19), referring to the dead in the land of Yisrael. Then "my dead body shall arise" (Ibid.), meaning the dead outside Yisrael. For all that, only the bodies of Yisrael, buried (in Yisrael), shall rise, but not bodies from other nations, which defile the land.

Rabbi Yochanan asks, Who conducts the body to the land of Yisrael? Rabbi Zeira said, The Holy One, blessed be He, digs caverns under the ground and they roll to the land of Yisrael. Hence it is written, "And the earth shall cast out the shades of the dead" (Isaiah 26:19).

The Holy One, blessed be He, will return that very body and that very soul to the world as before, and renew the face of the world. This is according to the verse, "The dead men of your people shall live, my dead body shall arise" (Isaiah 26:19). The same soul is stored before the Holy One, blessed be He, as it returns to its proper place after death according to its deeds, as it is written, "And the spirit returns to Elohim who gave it." At that time, He will revive the dead and pour dew from His head upon them. All the bodies will be resurrected from the dust by that dew.

It is written, "For your dew is as the dew on herbs (lit. 'of lights')" (Isaiah 26:19). What is the dew of lights? These are real lights, the Lights of above, by which He will pour life upon the world, because the Tree of Life will then provide never-ending life. For now, there is an end to life, since the evil serpent has its way, the moon is covered, namely the union of the supernal sun and moon, Zeir Anpin and Nukva, stops. For that reason, the water as it were, stops flowing. Therefore, life does not exist properly in the world.

The Refaim (shades) are the fourth group (of the erev rav). If they notice a time of distress coming upon Yisrael, they abandon them. Even if they have the power to save them, they do not want to do so. They abandon the Torah and those who study it. Instead, they do favors to those who worship idols. Of them, it is written: "The shades of the dead (Heb. refaim) shall not rise" (Isaiah 26:14), (i.e. at the resurrection of the dead). When The Children of Yisrael are visited (to be redeemed), it is written about them: "And made all their memory to perish" (Ibid.).
