What is the Law of Abraham in the Bible?

Answer 1

There was no 'Law of Abraham'. The Law code was established with Moses. There was, however, a 'covenant' made with Abraham which lasted 430 years until the Mosaic Law began as Israel left Egypt.(Exodus 12:40-42)(Galatians 3:17).

Answer 2

The Law of Abraham in The Bible refers to the covenant made between God and Abraham, where Abraham was promised numerous descendants and that his descendants would be as numerous as the stars in the sky. This covenant is a central promise in the Old Testament and is seen as the foundation of the relationship between God and the Jewish people.
