And so the Kuzari explains, certainly it’s everybody’s Hashem, but Hakadosh Baruch Hu chooses to rest His Presence on those people who are closest to Him. The navi is a man of greater perfection because of his achievements in nevuah. And so, when Shaul spoke to Shmuel Hanavi he said, “your G-d,” because he was saying, “Hashem is resting His Presence on you more than me! You have an excellence, a shleimus of character, and that makes the Shechina rest on you even more than upon me.”
So you’ll say, “The Shechina? That’s only a mashal. The Shechina actually rests on him?!”
And we say yes! Yes and yes! We’re learning now that the Shechina actually rests on the chachmei haTorah. And that’s why when you bring yourself close to talmidei chachomim, to those upon whom the Shechina rests most intensely, so in a sense it’s considered like you’re bringing yourself close to Hashem.
That’s why the Rambam (Deios 6:3) says that we should all strive as much as possible to be close to the chachomim רּוּבƒח י≈ינƒמ לָכ¿ּב – with all forms of closeness. To walk with them, to eat together with them, to do business with them. As much as possible, in whatever way you can imagine, to be physically close to them, and to thereby be close to Hashem.
