Galatians 3:20

Is not a mediator of one (eno ouk estin). That is, a middleman comes in between two. The law is in the nature of a contract between God and the Jewish people with Moses as the mediator or middleman. But God is one (o de qeo ei estin). There was no middleman between God and Abraham. He made the promise directly to Abraham. Over 400 interpretations of this verse have been made!
