I find Isaac's story so interesting. Firstly, Abraham trusts God in everything, and must choose a woman for his son who is from his own family. He cannot choose a Canaanite. Secondly, once Rebekah is chosen to be Isaac's wife, she is the last person who knows that she is to be his wife. It was very customary for marriages to be arranged in secret without the knowledge of the man and woman in question. Though Isaac probably knew what Abraham's servant was off to do, Rebekah did not know that she was to be his wife until after everyone else in her family knew.
