'My Statutes and My Commandments' in the Bible

If you will walk in my ways by keeping my statutes and my commandments, as David your father walked, then I will lengthen your days."

It shall be that if you listen to all that I command you and you walk in my ways and you do right in my eyes by keeping my statutes and my commandments, as David my servant did, then I will be with you, and I will build an enduring house for you as I built for David, and I will give Israel to you.
