Rebuking the impetuous[1]
ראובן בכורי אתה כחי וראשית אוני יתר שאת ויתר עז: פחז כמים אל-תותר כי עלית משכבי אביך אז חללת יצועי עלה
Reuven, you are my firstborn, my strength, the first of my vigor. [Potentially][2] exceeding in position and exceeding in might. Hasty as water, you will not exceed, since you went up on your father’s bed. Then you profaned that which went upon my couch[3]
As Yaakov’s life was ending, he took the opportunity to give his children their final blessings. While accenting their unique traits, he also informed them of their shortcomings. He started with his firstborn Reuven by rebuking him for an incident that had happened decades earlier[4]. When Yaakov’s wife Rochel died, he moved his bed into Rochel’s maidservant Bilhah’s tent. Reuven felt this was an affront to his mother Leah, who should have become Yaakov’s primary wife. Reuven audaciously moved his father’s bed out of Bilhah’s tent and put it into Leah’s[5]. At the time, Yaakov said nothing. Now that Yaakov’s life was ending, it was now or never to rebuke Reuven.
