Kabbalah su Isaia 25:9

The verse states: "And he called his name Noah, saying: This..." (Gen. 5:29). Why does the verse read, "saying: This?" The word "saying" refers to the Female Principle (Malchut) while "This" refers to the Righteous. It is written here and elsewhere, "This one shall comfort us" (Ibid.), "This is Hashem; we have waited for Him" (Yeshayah 25:9). Blessed are the righteous who are marked with the imprints of the ring of the King, for they are marked with His name. And He has put "names on earth, so that everything can be called by its name correctly.

At that time, the Righteous will attain complete knowledge, for as Rabbi Yosi said, When "Hashem rejoices in His works," then the Righteous are destined to grasp the Holy One, blessed be He, in their hearts. And wisdom will abound in their hearts, as if they are seeing Him with their eyes. This is the meaning of the verse: "And it shall be said on that day, this is our Elohim" (Isaiah 25:9). And for their existence together, the soul shall delight in the body more than anything, and that they shall have knowledge and perception of their Master, and shall have the enjoyment of the splendor of the Shechinah. This is the goodness hidden for the Righteous in the future to come. Thus, "And these are the generations of Isaac, Abraham's son," refers to the generations of gladness and laughter that will exist at that time. Abraham's son is the soul worthy of it and is perfect in its ascent; "Abraham begot Isaac," means that the soul sires joy and laughter in the world.
