'Keep My Statutes' in the Bible

And if you will walk in my ways, to keep my statutes and my commandments, as your father David did walk, then I will lengthen your days.

And 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 judgments:

Because they have forsaken me, and have worshiped Ashtoreth the goddess of the Sidonians, Chemosh the god of the Moabites, and Milcom the god of the children of Ammon, and have not walked in my ways, to do that which is right in my eyes, and to keep my statutes and my judgments, as did David his father.

And it shall be, if you will hearken unto all that I command you, and will walk in my ways, and do what is right in my sight, to keep my statutes and my commandments, as David my servant did; that I will be with you, and build you a sure house, as I built for David, and will give Israel unto you.
