Rabbi Aba explains the deep meaning of God's blessing of Abraham in all things, blessing him with Yesod. In the future the blessing on earth will prevail at all times because the blessing is first established above.
192. In addition, Rabbi Aba said that it is written: "And Hashem had blessed Abraham in all things (Heb. bacol)" (Beresheet 24:1). It is written: "For all (Heb. col) that is in heaven and on earth" (I Divrei Hayamim 29:11), MEANING THAT HE BLESSED ABRAHAM WITH THE SFIRAH OF YESOD CALLED COL, WHICH GIVES TO AND BLESSES THE SFIRAH OF MALCHUT. IT IS WRITTEN: "FOR ALL (HEB. KOL) THAT IS IN HEAVEN AND ON EARTH." THAT COL THAT IS YESOD RECEIVES FROM HEAVEN, WHICH IS ZEIR ANPIN, AND SUPPLIES EARTH, WHICH IS MALCHUT. It is also written: "In this way (Heb. coh) you shall bless" (Bemidbar 6:23), OF WHICH THE EXPLANATION IS THAT THE PRIESTS SHALL BLESS MALCHUT THAT IS CALLED COH. The reason is that for the sake of Yisrael, this Coh is blessed through the priest, in order that Yisrael below shall get blessed and the blessing shall be prevalent in everything. Of the future to come, it is written: "May Hashem bless you out of Zion..." (Tehilim 134:3) and "blessed be Hashem out of Zion, he who dwells in Jerusalem" (Tehilim 135:21), MEANING THAT MALCHUT WILL HAVE NO NEED TO BE BLESSED FIRST. RATHER, THE BLESSING WILL ALWAYS BE PRESENT IN HER. ZION IS THE INNER PART AND JERUSALEM IS THE SECRET OF THE OUTER PART OF MALCHUT.
