'Observing' in the Bible

I'm doing this because they have abandoned me and worshipped that Sidonian goddess Astarte, the Moabite god Chemosh, and the Ammonite god Milcom. They haven't lived my way by doing what I consider to be right and observing my statutes and my ordinances, like his father David did.

If you listen to everything that I command you to do, and if you live your life my way, and if you do what I consider to be right by observing my statutes and my commandments, just like my servant David did, then I will be with you, I will build an enduring dynasty for you, just like I did for David, and I'll give Israel to you.
