7 Now the blessed Jacob speaks to the following effect in his benedictions, testifying prophetically of our Lord and Saviour: “Judah, let your brethren praise you: your hand shall be on the neck of your enemies; your father's children shall bow down before you. Judah is a lion's cub: from the shoot, my son, you are gone up: he stooped down, he couched as a lion, and as a lion's cub; who shall rouse him up? A ruler shall not depart from Judah, nor a leader from his thighs, until he come for whom it is reserved; and he shall be the expectation of the nations. Binding his ass to a vine, and his ass's colt to the vine tendril; he shall wash his garment in wine, and his clothes in the blood of the grapes. His eyes shall be gladsome as with wine, and his teeth shall be whiter than milk.”
