Genesis 49:3-4, 8

Reuben, thou art my firstborn, my might, and the beginning of my strength, The excellency of dignity, and the excellency of power: Unstable as water, thou shalt not excel; Because thou wentest up to thy father's bed; Then defiledst thou it: he went up to my couch.

Judah, thou art he whom thy brethren shall praise: Thy hand shall be in the neck of thine enemies; Thy father's children shall bow down before thee.
