Abraham had a special worker that looked after everything that Abraham owned. One day, Abraham said to his worker, “I want you to find a wife for my son Isaac. My countrymen have a promise ceremony and this is what we do when we make a strong promise. Come here and put your hand on my leg and promise me that you will not get a wife for my son from the Canaanite families in this country. I want you to say that promise out loud so that the God who made heaven and earth hears what you say and is a witness.
