17 I will praise Jehovah according to his righteousness; and I will sing to the name of Jehovah, Most High As the design of God in the deliverances which he vouchsafes to his servants is, that they may render to him in return the sacrifices of praise, David here promises that he will gratefully acknowledge the deliverance which he had received, and at the same time affirms that his preservation from death was the undoubted and manifest work of God. He could not, with truth, and from the heart, have ascribed to God the praise of his deliverance, if he had not been fully persuaded that he had been preserved otherwise than by the power of man. He, therefore, not only promises to exercise the gratitude which was due to his deliverer, but he confirms in one word what he has rehearsed throughout the psalm, that he is indebted for his life to the grace of God, who had not suffered Saul to take it from him. The righteousness of God is here to be understood of his faithfulness which he makes good to his servants in defending and preserving their lives. God does not shut up or conceal his righteousness from our view in the secret recesses of his own mind, but manifests it for our advantage when he defends us against all wrongful violence, delivers us from oppression, and preserves us in safety although wicked men make war upon us and persecute us.
