Judah is a lion's whelp: from the prey, my son, you are gone up: he stooped down, he crouched as a lion, and as a lioness; who shall rouse him up?
All Commentaries on Genesis 49:9 Go To Genesis 49
Ambrose of Milan
AD 397
“A lion’s whelp is Judah.” Isn’t it clear that he represented the Father and manifested the Son? Is there any clearer way to teach that God the Son is of one nature with the Father? The one is the lion, the other the lion’s whelp. By this paltry comparison, their unity in the same nature and power is perceived. King proceeds from king, a strong one from one who is strong. Because Jacob foresaw that there would be those to claim that the Son was younger in age, he replied to them by adding, “From my seed you have come up to me. Resting you have slept like a lion and like a whelp.” And in a different passage you find that the whelp is himself “the lion of the tribe of Judah.” … But the Son is not being named in such a way as to be separated from the Father. Jacob, who confesses the Son, also esteems him equal. Moreover, he represented the Son’s incarnation in a wonderful fashion when he said, “From my seed you have come up to me.” For Christ sprouted in the womb of the Virgin like a shrub upon the earth; like a flower of pleasing fragrance, he was sent forth in the splendor of new light and came up from his mother’s vitals for the redemption of the entire world. Just so, Isaiah says, “There shall come forth a rod out of the root of Jesse, and a flower shall come up out of the root.” The root is the household of the Jews, the rod is Mary, the flower of Mary is Christ. She is rightly called a rod, for she is of royal lineage, of the house and family of David. Her flower is Christ, who destroyed the stench of worldly pollution and poured out the fragrance of eternal life.
