Jacob's blessing of Joseph reaches into cosmic language. Targum Pseudo-Jonathan preserves two divine titles worth pausing on. "From the Word of the Lord shall be thy help; and He who is called the All-Sufficient shall bless thee" (Genesis 49:25).
The first title — Memra d'Adonai, the Word of the Lord — is the Targum's preferred way of speaking about God's active presence in the world without saying God's name directly. When the Torah says God acted, the Targum often says the Memra acted. It is a theology of divine nearness that maintains reverent distance.
The second title is El Shaddai — the "All-Sufficient," the God who says dai ("enough") to chaos, to famine, to every force that tries to press beyond its bounds. This is the name under which the Holy One first appeared to Abraham (Genesis 17:1), the covenantal name of patriarchal promise.
The blessings that follow come from two directions. "The blessings which descend with the dew of heaven from above, and with the good blessing of the fountains of the deep which ascend and clothe the herbage from beneath." Rain falling, springs rising. Joseph stands at the meeting point. And the Targum adds the most human line of all: "the breasts at which thou wast suckled, and the womb in which thou didst lie" — blessings on Rachel, remembered one last time.
