Genesis 49:13-15

NHEB(i) 13 Zebulun will dwell at the seashore, and he will be a harbor for ships, and his border will be at Sidon. 14 Issachar is a strong donkey lying down between the saddlebags. 15 When he sees a good resting place, that the land is pleasant, he will bend his back to the burden, and become a slave doing forced labor.
