25 Even by the God of thy father, who shall help thee; and by the Almighty, who shall bless thee with blessings of heaven above, blessings of the deep that lieth under, blessings of the breasts, and of the womb: 26 The blessings of thy father have prevailed above the blessings of my progenitors unto the utmost bound of the everlasting hills: they shall be on the head of Joseph, and on the crown of the head of him that was separate from his brethren.
In the previous verses Jacob had described Joseph as a bough rooted in a permanent fountain of water. He continues those analogies of nourishment by calling to mind an infant and the breasts and womb of its mother.
The womb, with its umbilical cord, represents a direct tether to God. It is our innate understanding of what is good, our childlike certainty of self-worth, our conscience ever reminding us of our divine self. For those that believe that the immortal spirit has existed since before we were born, the womb could also be representative of a pre-earth existence directly in the presence of our Heavenly parents.
The breasts represent the more active side of our discipleship. After the womb a child changes from receiving nourishment directly to now having to work for it. This is our need to constantly return to truth, to dispel the sophistry that surrounds us in the world, to regain hope in the face of cynicism, to unburden our personal sins and shame. We do not do those things only once. We get renewed and then we get renewed again and again.
Innate and constant good, and sources of replenishing and nourishing, these are the blessings that Jacob pronounces upon Joseph. Then Jacob testifies in verse 26 that it is these blessings which have elevated and set him apart in his life. It was these sources of good that raised him to a higher station than anyone in his family had ever known before, and it was what elevated and distinguished Joseph above his brethren. So, too, countless testimonies have attested that it is this grace and goodness of God, the constant nourishment and refreshing of His love, that has made all the difference in the lives of the sincere and the saved. It is God that has taken us from being broken and ashamed, and has made us into His sons and daughters instead.
