Verse 18. - And he came unto his father, - by this time a bed-ridden invalid (vide ver. 19) - and said, My father. If he attempted to imitate the voice of Esau, he was manifestly unsuccessful; the dull ear of the aged patient was yet acute enough to detect a strangeness in the speaker's tone. And he said, Here am I who art thou, my son? "He thought be recognized the voice of Jacob; his suspicions were aroused; he knew the crafty disposition of his younger son too well; and he felt the duty of extreme carefulness" (Kalisch).

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.And he came unto his father,.... Into the tent and apartment where he was:

and said, my father; to try whether he was awake, and to let him know that he was come, since he could not see him:

and he said, here am I; what hast thou to say to me?

who art thou, my son? for, from the voice and the quick dispatch made, he suspected it was not his son Esau.
