Genesis 49:13-15

King James Version

¹³ Zebulun shall dwell at the haven of the sea; and he shall be for an haven of ships; and his border shall be unto Zidon.

¹⁴ Issachar is a strong ass couching down between two burdens:

¹⁵ And he saw that rest was good, and the land that it was pleasant; and bowed his shoulder to bear, and became a servant unto tribute.
