18 And he cometh in unto his father, and saith, 'My father;' and he saith, 'Here 'am' I; who 'art' thou, my son?' 19 And Jacob saith unto his father, 'I 'am' Esau thy first-born; I have done as thou hast spoken unto me; rise, I pray thee, sit, and eat of my provision, so that thy soul doth bless me.' 20 And Isaac saith unto his son, 'What 'is' this thou hast hasted to find, my son?' and he saith, 'That which Jehovah thy God hath caused to come before me.' 21 And Isaac saith unto Jacob, 'Come nigh, I pray thee, and I feel thee, my son, whether thou 'art' he, my son Esau, or not.' 22 And Jacob cometh nigh unto Isaac his father, and he feeleth him, and saith, 'The voice 'is' the voice of Jacob, and the hands hands of Esau.' 23 And he hath not discerned him, for his hands have been hairy, as the hands of Esau his brother, and he blesseth him, 24 and saith, 'Thou art he—my son Esau?' and he saith, 'I 'am'.'

(Read Genesis 27:18-29)
Jacob, with some difficulty, gained his point, and got the blessing. This blessing is in very general terms. No mention is made of the distinguishing mercies in the covenant with Abraham. This might be owing to Isaac having Esau in his mind, though it was Jacob who was before him. He could not be ignorant how Esau had despised the best things. Moreover, his attachment to Esau, so as to disregard the mind of God, must have greatly weakened his own faith in these things. It might therefore be expected, that leanness would attend his blessing, agreeing with the state of his mind.
