25 Then he said, "Bring it to me, that I may eat of my son's game and bless you." So he brought it to him, and he ate; and he brought him wine, and he drank. 26 Then his father Isaac said to him, "Come near and kiss me, my son." 27 So he came near and kissed him; and he smelled the smell of his garments, and blessed him, and said, "Ah, the smell of my son is like the smell of a field that the Lord has blessed. 28 May God give you of the dew of heaven, and of the fatness of the earth, and plenty of grain and wine. 29 Let peoples serve you, and nations bow down to you. Be lord over your brothers, and may your mother's sons bow down to you. Cursed be everyone who curses you, and blessed be everyone who blesses you!"
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.
