Jacob's blessings for his sons in Genesis 49 were more like descriptions of the men and prophecies concerning their descendants.

Reuben: Unstable power.
Simeon and Levi: Cruel, angry.
Judah: Cradle of Kings.
Zebulun: Traveler, trader.
Issachar: Laborers, slaves.
Dan: Judge, snake.
Gad - Comeback kid.
Asher - Good food and drink.
Naphtali - Athletic, artsy?
Joseph - Fruitful, blessed, strong.
Benjamin - Wolf, conqueror.

Some of these descriptions can be seen playing out in history either in the way the tribes behaved or the way others behaved toward them. Others are more...enigmatic.
