Q. Jacob said to Rebekah that if Isaac found out he wasn’t Esau, it would bring a curse to him. Rebekah responded that let the curse be on her. Was there ever a curse on Rebekah in the end?
A. Isaac did not curse Jacob, because he himself said, “Cursed be those who curse you” (Gen 27:29), and he knew Jacob shall be blessed (Gen 27:33).
He did not curse Rebekah either, probably because he loved her (Gen 24:67), and likely knew that she was more aligned with God’s choice of the younger than he was, as he favored the older (Gen 25:28).
Her “curse” came in the form that she never saw her favorite son Jacob again. She thought she was sending Jacob away only a short time – a few days with Laban plus the duration for the return trip:
• Gen 27:43-45 Now therefore, my son, obey my voice, and arise, flee to Haran, to my brother Laban! Stay with him a few days, until your brother’s fury subsides, until your brother’s anger against you subsides and he forgets what you did to him. Then I will send and get you from there.
In fact Jacob stayed with Laban 20 years – 7 years for Leah, 7 years for Rachael, and 6 years for the sheep and goats:
• Gen 31:38 These twenty years I have been with you; your ewes and your female goats have not miscarried, nor have I eaten the rams of your flocks.
By the time Jacob returned, Rebekah already died. She never got to see him again for her trickery. Sin always pays.
