18 And he came to his father, and said, My father! And he said, Here am I: who art thou, my son? 19 And Jacob said to his father, I am Esau, thy firstborn. I have done according as thou didst say to me. Arise, I pray thee, sit and eat of my venison, in order that thy soul may bless me. 20 And Isaac said to his son, How is it that thou hast found [it] so quickly, my son? And he said, Because Jehovah thy God put [it] in my way. 21 And Isaac said to Jacob, Come near, I pray thee, that I may feel thee, my son, whether thou be really my son Esau or not. 22 And Jacob drew near to Isaac his father; and he felt him, and said, The voice is Jacob's voice, but the hands are the hands of Esau. 23 And he did not discern him, because his hands were hairy, as his brother Esau's hands; and he blessed him. 24 And he said, Art thou really my son Esau? And he said, It is I.

(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.
