John Gill Commentary Genesis 27:13

"And his mother said unto him, Upon me be thy curse, my son. Only obey my voice, and go fetch me them." — Genesis 27:13 (ASV)

And his mother said to him, upon me [be] your curse, my son , &c.] That is, if your father should curse you, which I am well assured he will not, let the curse, be what it will, fall upon me, and not on you; I shall bear the blame and the punishment: this she said in the strong faith of the divine oracle, being fully persuaded her scheme would succeed, and that Jacob would have the blessing, and therefore she feared no curse falling upon her or her son; and this she said to encourage him: the Targum of Onkelos is, to me it has been said in prophecy, that the curses shall not come upon you, my son:

only obey my voice, and go fetch me [them] ; the two fat kids of the goats from the flock.
