To Whom Shall We Compare Jacob?

I need your help. I want to crowd source part of my coming sermon. I’m preaching on Genesis 28:10-19a, the story of “Jacob’s Ladder.” My usual summary of Jacob’s character is that he is not someone you would want to buy a used car from, However, Tim Holm has pointed out to me that I’m hard on car salesmen (although he says I’ve been getting better*). At any rate, describing Jacob as someone you wouldn’t want to buy a used car from is out. I need another description. Any suggestions?

*Perhaps because I had such a wonderful experience buying a used Toyota Camry from Holm Chevrolet. I’ll admit that this is a shameless plug, but we really did have a wonderful car buying experience.
