Issachar is a strong-boned ass, crouching among the sheepfolds. When he saw how good was security, and how pleasant was the country, he bent his shoulder to the burden, and became a toiling serf. Genesis 49, 14-15

Dan shall   govern his people, as one of the tribes of Israel. Dan shall be a serpent by the road, a viper by the path, that bites the horse’s heels so that his rider is thrown backward. I wait for Your  deliverance, O LORD.          Genesis 49, 16-18

Zebulun shall dwell by the seashore; he shall be a haven for ships, and his flank shall rest on Sidon.                   Genesis  49-13     

Josesh is a wild ass, a wild ass by   a spring-wild colts on a hillside. Archers bitterly assailed him; they shot at him and harried him. Yet his bow stayed taut, and his arms were made firm by the hands of the Mighty One of Jacob-there, the Shepherd, the Rock of Israel-the God of your father who helps you, and Shaddai who blesses you with blessings of heaven above, blessings of the deep that couches below, blessings of the breast and womb. The blessings of your father surpass the blessings of my ancestors, to the utmost bounds of the eternal hills. May they rest on the head of Joseph, on the brow of the elect of his  brothers:                                              Genesis49, 22-26                                                                                                 

You, O Judah, your brothers shall praise; your hand shall be on the nape of your foes; your father’s sons shall bow low to you. Judah is a lion’s whelp; on prey, my son,   have     you grown. He crouches, lies down like a lion, like the king   of beasts-who dare   rouse him?  The scepter shall not depart from Judah, nor the ruler’s staff from between his feet; so that tribute shall come to him and the homage of peoples   be   his. He tethers his ass to a vine, his ass’s foal to a choice vine; he washes his garment in wine, his robe in blood of grapes. His eyes are darker than winehis teeth are whiter than milk.;                   
Genesis 49, 8-12                                                                                                                 

Gad shall be raided by raiders, but he shall raid at their heels. Genesis 49, 19

Asher’s bread shall be rich , and he shall yield royal dainties.
Genesis 49, 20
