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 discerned him not,.... As he could not see, he could make no judgment by that sense; and, though he had his hearing, and thought the voice was like Jacob's, he might imagine there might be an alteration in Esau's voice, coming in haste and weary from the fields; yet, as there could not be any deception in his feeling, he thought it safest to trust to that, as it follows:
because his hands were hairy as his brother Esau's hands; which could not in a short time become so naturally; it was more reasonable to think that Esau's voice should be altered and become like Jacob's, than that Jacob's hands should become like Esau's:
so he blessed him; or intended and determined within himself to bless him, for the blessing was not given till afterwards; unless this is to be understood of a common blessing, congratulating him on the quick dispatch he made, and the great success he met with; and after this gave him the patriarchal blessing, which as yet he had not, being not thoroughly satisfied of him, as appears by what follows.
