אָנֹכִ֗י אֵרֵ֤ד עִמְּךָ֙ מִצְרַ֔יְמָה וְאָנֹכִ֖י אַֽעַלְךָ֣ גַם־עָלֹ֑ה וְיוֹסֵ֕ף יָשִׁ֥ית יָד֖וֹ עַל־עֵינֶֽיךָ׃
Yo descenderé contigo á Egipto, y yo también te haré volver: y José pondrá su mano sobre tus ojos.
Kedushat Levi
Genesis 46,4. “I will descend to Egyt with you, and I will also ascend with you.” In order to understand this verse properly, we must remember the pedagogic rule that when a teacher is confronted with a student of limited intellect, he must endeavour to rein in his superior intellect and descend to the level of the student. When faced with a student who has a brilliant mind, the teacher need not impose any restrictions on himself when teaching such a student. As long as Yaakov resided in the Holy Land, his intellect was very strong; he was afraid that now that he would “descend” to Egypt, he would experience a reduction in intellectual capacity so that G’d would “restrain” Himself when communicating with him, so that he would not be able to serve Him in the manner he was used to. G’d reassured him here that he need not have any such concerns, as the Shechinah would remain at his side as long as he would be in Egypt.
G’d promises Yaakov that upon his return to the Holy Land, he will have attained great spiritual stature. This is the meaning of the words: גם עלה. When the Shechinah which had accompanied him “down” to Egypt, would return to the Holy Land, [which had not contained any Jews during the interval, so that these had not been deprived of its Presence, Ed.], Yaakov would participate in this elevation, עליה.

Sefat Emet
Regarding the verse "lest they multiply, etc., and join also, etc., and go up from the land"—Rashi explained it in two ways. And I have already written elsewhere that the two interpretations are really one: when the holy sparks [nitzotzei kedushah] ascend from these places, automatically all evildoers are scattered and [Israel] comes to redemption. This is the hint in the Masoretic tradition: [Proverbs 11:24] "there is one who scatters yet increases more" [yesh mefazer venosaf od]. But one can explain further: "venosaf od" [and increases more]—beyond the holy sparks ascending from the sitra achra [the Other Side] and being added to holiness, there is something even greater: through the ascent of the holy sparks, an additional light comes from above. This is like what they said [Berachot 34b]: "In the place where penitents [ba'alei teshuvah] stand, even the completely righteous cannot stand." And just as after the Exodus from Egypt there was the receiving of the Torah from Heaven—this is "venosaf od" [and increases more], for "od" [more] means above nature, as I wrote above in parashat Vayigash. This is what is said [Genesis 46:4]: "I will go down with you to Egypt, and I will also surely bring you up [a'elcha gam aloh]"—"gam" [also] refers to additions, as it says "venosaf gam hu" [and join also]. This alludes to "itkasya" [hiddenness] and includes both: the holy sparks that are hidden and submerged within the kelipot [husks/shells], and also the hidden and concealed light above. And through the ascent of the holy sparks, one merits to draw down the hidden and concealed light from above, as I wrote elsewhere.
