Genesis 49:13-15

13“Zebulun will live by the seashore and become a haven for ships; his border will extend toward Sidon.

14“Issachar is a rawboned Or strong donkey lying down among the sheep pens. Or the campfires; or the saddlebags

15When he sees how good is his resting place and how pleasant is his land, he will bend his shoulder to the burden and submit to forced labor.
