Reuben: Loss of Primacy

Genesis 49:3-4

Reuben, thou art my first-born, my might, and the beginning of my strength; The pre-eminence of dignity, and the pre-eminence of power.

Boiling over as water, thou shalt not have the pre-eminence; Because thou wentest up to thy father’s bed; Then defiledst thou it: he went up to my couch.
