Kabbalah su I Samuele 3:10

Tosefta Why is "Noah Noah" (Gen. 6:9) written twice? Each and every righteous person in the world has two spirits. One stays in this world, while the other is in the World to Come. And so we find that the Holy One, blessed be He, named all the righteous twice: "Moses, Moses" (Ex. 3:4), "Jacob, Jacob" (Gen. 46:2), "Abraham, Abraham" (Gen. 22:11), "Samuel, Samuel" (I Shmuel 3:10) with the exception of Isaac. He is not named twice because when he approached the altar to be sacrificed, the soul that was within him in this world left him. And because it is said of Abraham, "blessed are You who resurrect the dead", so only the soul of the World to Come was returned to him. And that is why you shall find that the name of the Holy One, blessed be He, was not unified (on any righteous person in his lifetime). It was unified only on Isaac, because he was already considered as dead. He was like those who pass away from this world. The verse therefore states: "Behold, He puts no trust in His holy ones" (Iyov 15:15) because He does not unify His name on the righteous during their lifetimes.

But come and behold, "and his spirit was troubled (Heb. וַתִּפָּעֶם)" corresponds to "And the spirit of Hashem began to move him (Heb. לְפַעֲמוֹ)" (Judges 13:25), for the spirit would appear and disappear, come and go, yet not settle upon him properly. It is therefore written, "And the spirit of Hashem began to move him," when (the spirit) just began (to inspire him). Here also the spirit would appear and leave, then appear, but would not settle upon him, so that he could understand. Of Nebuchadnezzar it is written, "and his spirit was troubled (Heb. וַתִּתְפָּעֶם)," for the inspiration was twice as strong. It would come and go, as it is written, "as on previous occasions (Heb. כְּפַעַם בְּפַעַם, lit. 'as time to time')" (I Shmuel 3:10), now upon this and now upon that, but his mind was not settled.

And this the secret that they teach "Ad-nai Ad-nai" (Exodus 34) there is a pause between them. In every place that a name is called twice there is a pause between them, such as "Avraham, Avraham" (Gen. 22:11); "Yaakov, Yaakov" (Gen. 46:2); "Shmuel, Shmuel" (I Samuel 3:10). All have a pause between them, with the exception of "Moshe Moshe", which has no pause between them. What is the reason? "Avraham, Avraham" - the last is complete, the first not. At first he was not complete since now he became complete through ten tests, and therefore there is a pause between them, since now he was not as he was at the beginning.
