Chasidut do Wyjścia 33:16

Dawidh had no vitality at all, for he ought to have been a Nefel/miscarriage/fallen-out. But Adam haRishon [A"hR] gave him seventy of his own years, as our rabbis z"l have said. For, the life of A"hR was drawn from the aspect of Arikh Anpin [A"A, the Supernal “Long Face”], which is the aspect of arikhath apayim/forbearance [lit. lengthening of nose], the aspect of the aforementioned stories of shanim qadhmoniyoth [ancient years, ancient aspects] etc. And as transmitted in the [Arizal’s] writings, that the vitality of the first generations was from there, from the aspect of A"A; and therefore they would live very long lives. And all the stories that the Torah tells about the first generations, are all from the aspect of stories of shanim qadhmoniyoth, which are the aspect of hadrath panim/honorable face, as all the seventy faces of the Torah receive from it. And therefore the Torah began from these holy stories, before it explains the mitzwoth of the Torah. For, all the mitzwoth of the Torah, which consist of the aspect of the seventy faces of the Torah, need to receive from the aspect of hadrath panim, the aspect of shufreih de’Adam/Man’s beauty, the aspect of stories of shanim qadhmoniyoth and the essential holy vitality that is drawn from there. This renews his vitality at all times; each moment he begins living anew, which is the aspect the (Ps. 2), “Ani hayom yelidhtikha/ Today I have begotten you,” that is said of the Mashiach [Anointed to Kingship] Dawidh. Namely, Dawidh Mashiach merited that it was reversed to good, from one opposite to the other. For, just as initially he had no vitality at all and really ought to have been a Nefel, the thing was reversed and he merited to live seventy years from A"hR’s years, and merited to live all the seventy years in the aspect of new life at all times, as if he had still never lived at all, but was just born today. And he, at all times was like a miscarriage that was born now, which has no life and has to receive, by Hashem’s graces, new life. And so on, at every time and moment. And thus he lived all his seventy years, which is the essence of life, as mentioned above. Until he merited through his devotion and effort in this aspect — trying and toiling all his days without sleeping his days away, but rather adding holiness and consciousness at all times — to renew his vitality at every hour. Until he merited thereby to live long, everlasting life for ever and ever, in the aspect of “Dawidh Melekh Yisrael Chai Vekayam/Dawidh, King of Yisrael, is alive and enduring,” as mentioned. And this is the aspect of tefillin, as mentioned. For teFiLYn are a term for (Ex. 33:16), “VeniFLiYnu ani ve`amekha/ and I and Your people are distinguished,” which was said when Hashem Yithbarakh revealed to him the Thirteen Attributes of Mercy, which are the aspect of the light of the tefillin, which is the aspect of the “Ve'raitha eth-achorai/ and you shall see My back” stated there, which is the tefillin knot (Berakhoth 7), which is where the root of Dawidh-Mashiach’s soul is, as mentioned, as he ought to have been Nefel as mentioned, but now he merited the thing being reversed to good and living new life at all times, as if he was born today, which is the aspect of tefillin, the aspect of “Venifliynu ani ve`amekha,” for the thing becomes reversed, as mentioned, and is made from the aspect of Nefel into the aspect of Venifliynu, which is the aspect of tefillin, which is the aspect of the aforementioned long life/longevity of Dawidh as mentioned. And therefore Mashiach is called “Bar Nifli/ My Distinguished Son” [Sanh. 96b on Amos 9:11] for Mashiach will attain that life, which is the aspect of the “Ani hayom yelidhtikha” that is said of Mashiach, and as mentioned above.
