Conscious he would soon be passing from this scene as we all do, Jacob blessed his son Judah.
That blessing is poetic, prophetic and open to interpretation on multiple levels, the most significant of which is that he is
speaking in some measure of Jesus Christ, who was descended from Judah. One of
the things Jacob says of Judah’s offspring is this: “He has washed his garments
in wine, and his vesture in the blood of grapes.”
This is the first time any of the Bible’s writers associate wine with blood, though in this instance probably neither word is to be taken
literally.
