Genesis

³⁹And Isaac his father answered and said unto him, Behold, of the fatness of the earth shall be thy dwelling, And of the dew of heaven from above; ⁴⁰And by thy sword shalt thou live, and thou shalt serve thy brother; And it shall come to pass when thou shalt break loose, That thou shalt shake his yoke from off thy neck. ⁴¹And Esau hated Jacob because of the blessing wherewith his father blessed him: and Esau said in his heart, The days of mourning for my father are at hand; then will I slay my brother Jacob. ⁴²And the words of Esau her elder son were told to Rebekah; and she sent and called Jacob her younger son, and said unto him, Behold, thy brother Esau, as touching thee, doth comfort himself, purposing to kill thee. ⁴³Now therefore, my son, obey my voice; and arise, flee thou to Laban my brother to Haran; ⁴⁴and tarry with him a few days, until thy brother's fury turn away; ⁴⁵until 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 bereaved of you both in one day?
