4 I have made a covenant with my elect: I have sworn to David my servant: 5 Thy seed will I settle for ever. And I will build up thy throne unto generation and generation.29 I will keep my mercy for him for ever: and my covenant faithful to him. 30 And I will make his seed to endure for evermore: and his throne as the days of heaven. 31 And if his children forsake my law, and walk not in my judgments: 32 If they profane my justices: and keep not my commandments:33 I will visit their iniquities with a rod: and their sins with stripes. 34 But my mercy I will not take away from him: nor will I suffer my truth to fail.
