Genesis 27:19 - Wesley's Explanatory Notes

And Jacob said, I am Esau — Who would have thought this plain man could have played such a part? His mother having put him in the way of it, he applies himself to those methods which he had never accustomed himself to, but had always conceived an abhorrence of. But lying is soon learned. I wonder how honest Jacob could so readily turn his tongue to say, I am Esau thy first — born: and when his father asked him, Genesis 27:24. Art thou my very son Esau? to reply I am. How could he say, I have done as thou badst me, when he had received no command from his father, but was doing as his mother bid him? How could he say, Eat of my venison, when he knew it came not from the field, but from the fold? But especially I wonder how he could have the forehead to father it upon God, and to use his name in the cheat.
