Genesis 49:13-15

Leeser(i) 13 Zebulun shall dwell at the margin of the seas; and he shall be at the haven of ships; and his border shall be near to Zidon. 14 Issachar is a strong-boned ass, couching down between the stables. 15 And when he saw the resting-place that it was good, and the land that it was pleasant, he bent his shoulder to bear, and became a servant unto tribute.
