Comentario sobre Génesis 30:2

התחת means AM I IN HIS STEAD?

ויחר, because she had said: הבה לי!. This sounded as if Rachel’s having children was something within the power of her husband. His anger was on behalf of his Creator, G’d, Who had been insulted by Rachel’s words. He had to ignore his love and commiseration for Rachel’s plight seeing she had been guilty of such a fauz pas.

ויחר אף יעקב, Jacob became agitated, etc. Jacob's agitation was due to her having uttered a curse, i.e. declaring that she would die. When the righteous utter a curse, even conditionally, this makes an indelible impression. We know from Bereshit Rabbah 74,9 that Rachel died prematurely because Jacob himself uttered a curse when he decreed death on the thief who stole Laban's Teraphim. This is why the Torah added the word ברחל, i.e. on her account. He was also upset because she demanded children, הבה לי בנים, instead of having asked her husband to pray on her behalf.
