“Flee to Lavan, my brother in Charan. Stay with him for a while until your brother’s anger subsides. Until the anger of your brother subsides from you…” (Genesis 27:43-45).
Rabbi Abraham Twerski explains that these verses are not redundant. How was Jacob to know when his brother’s anger subsided? Proverbs 27:19 states that “Like one’s reflection is seen in water, so does one heart reflect another.” Emotions are reciprocal. Rebecca says that you’ll know when Esav’s anger has subsided when the anger subsides from you. When you feel your animosity for him leave, you’ll know he no longer hates you.
