Genesis 27:5

Rebekah heard. — She was possibly present when Isaac gave the order, and he may even have wished her to know his determination to give the blessing to his favourite son. But the words filled her with dismay. She had, no doubt, treasured the prophecy of Jacob’s ultimate superiority, and now it seemed as if the father would reverse it. Had her faith been pure and exalted, she would have known that God would fulfil His word without her help; but all alike act from unworthy motives, and all have their meed of punishment. But here the fault began with Isaac, and Rebekah probably considered that she was preventing a grievous wrong.
