25 Isaac said, "Bring the food so I can eat of my son's game and give you my personal blessing." Jacob brought it to him and he ate. He also brought him wine and he drank. 26 Then Isaac said, "Come close, son, and kiss me." 27 He came close and kissed him and Isaac smelled the smell of his clothes. Finally, he blessed him, Ahhh. The smell of my son is like the smell of the open country blessed by God. 28 May God give you of Heaven's dew and Earth's bounty of grain and wine. 29 May peoples serve you and nations honor you. You will master your brothers, and your mother's sons will honor you. Those who curse you will be cursed, those who bless you will be blessed.
Matthew Henry's Commentary on Genesis 27:25-29
Commentary on Genesis 27:18-29
(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.
