Genesis 27:37

And Isaac answered and said unto Esau ,.... Giving an account of the blessing be had bestowed upon his brother:

behold, I have made him thy lord ; the lord of his posterity, who would be subdued and become tributary to his seed:

and all his brethren have I given to him for servants ; the Edomites, who sprung from his brother Esau, who, according to this prophetic blessing, became servants to David, who was a son of Jacob's; see Gill on Genesis 27:29 ,

and with corn and wine have I sustained him ; promised him a fruitful country, the land of Canaan, abounding with all good things, particularly with corn and wine, which are put for all the rest:

and what shall I do now unto thee, my son ? what is there remains? what can be bestowed upon thee? there is nothing left; dominion over others, even over all nations, yea, over thyself and thy posterity, and plenty of all good things, are given already to Jacob; what is there to be done for thee, or thou canst expect?
