'Keep My Statutes' in the Bible

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

As for you, if you will walk before me, as David your father walked, in integrity of heart, and in uprightness, to do according to all that I have commanded you, and will keep my statutes and my ordinances;

It shall be, if you will listen to all that I command you, and will walk in my ways, and do that which is right in my eyes, to keep my statutes and my commandments, as David my servant did; that I will be with you, and will build you a sure house, as I built for David, and will give Israel to you.
