Genesis 49:1-4

1Then Jacob summoned his sons and said, “Assemble yourselves, so that I may tell you what will happen to you 1in the 2days to come.2Gather together and listen, sons of Jacob; Yes, 3listen to Israel your father.

3“Reuben, you are my firstborn, My might and 4the beginning of my strength, Preeminent in dignity and preeminent in power.45Uncontrollable as water, you shall not have preeminence, 6Because you went up to your father’s bed; Then you defiled it--he went up to my couch.
