Gen 49:1-2, 8-11: Then Jacob called his sons, and said, “Gather yourselves together, that I may tell you what shall befall you in days to come. 2 Assemble and hear, O sons of Jacob, and hearken to Israel your father. . . 8 Judah, your brothers shall praise you; your hand shall be on the neck of your enemies; your father’s sons shall bow down before you. 9 Judah is a lion’s whelp; from the prey, my son, you have gone up. He stooped down, he couched as a lion, and as a lioness; who dares rouse him up? 10 The scepter shall not depart from Judah, nor the ruler’s staff from between his feet, until he comes to whom it belongs; and to him shall be the obedience of the peoples. 11 Binding his foal to the vine and his ass’s colt to the choice vine, he washes his garments in wine and his vesture in the blood of grapes; 12 his eyes shall be red with wine, and his teeth white with milk.
