Matthew Henry on Genesis 27:18-29
Observe here, I. The art and assurance with which Jacob managed this intrigue. Who would have thought that this plain man could have played his part so well in a design of this nature? His mother having put him in the way of it, and encouraged him in it, he dexterously applied himself to those methods which he had never accustomed himself to, but had always conceived an abhorrence of.
