They say what goes around, comes around. Have you found that to be true in your life? Do the good things you do find their way back around to you? What about the bad? Some people call it karma. We in the Christian faith call it the Golden Rule. Do unto others as you would have them do unto you.
For that scoundrel Jacob, what goes around does indeed come back around. The tables have turned in an instant. Jacob, who was the trickster, now becomes the tricked.
