'Keep My Statutes' in the Bible

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

And if thou wilt walk before me, as David thy father walked, in integrity of heart, and in uprightness, to do according to all that I have commanded thee, and wilt keep my statutes and my judgments:

Because they have forsaken me, and have worshiped Ashtoreth the goddess of the Zidonians, 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 thou wilt hearken to all that I command thee, and wilt walk in my ways, and do right in my sight, to keep my statutes and my commandments, as David my servant did; that I will be with thee, and build thee a sure house, as I built for David, and will give Israel to thee.
