He ties his donkey to the vine,
Judah ties his donkey to the vine and washes his garments in wine, in a scene of lavish plenty.
It extends Judah's rule into imagery of abundance.
1Then Jacob called for his sons and said, “Gather around so that I can tell you what will happen to you in the days to come: 2Come together and listen, O sons of Jacob; 3Reuben, you are my firstborn, my might, 4Uncontrolled as the waters, 5Simeon and Levi are brothers; 6May I never enter their council; 7Cursed be their anger, for it is strong, 8Judah, your brothers shall praise you. 9Judah is a young lion— 10The scepter will not depart from Judah, 11He ties his donkey to the vine, 12His eyes are darker than wine, 13Zebulun shall dwell by the seashore 14Issachar is a strong donkey, 15He saw that his resting place was good 16Dan shall provide justice for his people 17He will be a snake by the road, 18I await Your salvation, O LORD. 19Gad will be attacked by raiders, 20Asher’s food will be rich; 21Naphtali is a doe set free 22Joseph is a fruitful vine— 23The archers attacked him with bitterness; 24Yet he steadied his bow, 25by the God of your father who helps you, 26The blessings of your father have surpassed 27Benjamin is a ravenous wolf; 28These are the tribes of Israel, twelve in all, and this was what their father said to them. He blessed them, and he blessed each one with a suitable blessing.
