Genesis 27:45
Until thy brother’s anger turn away from thee, and he forget that which thou hast done to him: then I will send, and fetch thee from thence: why should I be deprived also of you both in one day? Until thy brother’s anger turn away from thee, and he forget that which thou hast done to him: then I will send, and fetch thee from thence: why should I be deprived also of you both in one day?
Rebekah told Jacob to remain away only until Esau's anger turned away and he forgot what Jacob had done to him, when she would send and fetch him back from where he had gone, because she feared being deprived of both sons in one day. That anger followed Jacob's deception of his father Isaac to obtain the blessing intended for Esau, which Jacob did under Rebekah's wrong counsel. Jacob therefore left his father's home as a fugitive, fleeing Esau's wrath and threat against his life, troubled by remorse and fear of his brother.
Rebekah's plan to fetch Jacob back did not succeed, and the separation proved permanent, for she never saw him again. She repented in bitterness for what she had done in counseling the deception that forced Jacob to flee for his life and separated her from him forever. Esau's threat remained a source of danger years later, when Jacob was returning home and heard that Esau was approaching him with warriors. Isaac lived many years after giving Jacob the blessing and became convinced, from the subsequent course of Esau and Jacob, that the blessing rightly belonged to Jacob.
Deceptions like Jacob's are still practiced by men standing in high places of trust. They belong with partiality and hypocrisy, with handling men as machinery and binding their freedom, and with perverting right principles through selfishness and covetousness.
