Ps 17 (18)
This monumental ode, which the title attributes to David, is a Te Deum of the king of Israel, it is his hymn of thanksgiving to God because he has been delivered from all his enemies and from the hand of Saul. David acknowledges that God alone was his Deliverer, his Saviour.
David begins with a profession of love (v. 2). He shouts to the world his love for the Lord. The word he uses is 'rāḥam', meaning to love very tenderly, as in the case of a mother's love. The Lord is his strength. David is weak as a man. With God, who is his strength, he is strong. It is God's strength that makes him strong. This truth applies to every man. Every man is weak, and remains so unless God becomes his strength.
God for David is everything (v.3). The Lord for David is rock, fortress. He is his Deliverer. He is the rock in which he takes refuge. He is the shield that defends him from the enemy. The Lord is his mighty salvation and his bulwark. The Lord is simply his life, his protection, his defence. It is a true declaration of love and truth.
David's salvation is from the Lord (v. 4). It is not from his worthiness. The Lord is worthy of praise. God cannot but be praised. He does everything well. It is enough for David to call upon the Lord and he will be saved from his enemies. Always the Lord answers when David calls upon him. David's salvation is from his prayer, from his invocation.
Then David describes from what dangers the Lord delivered him. He was surrounded by billows of death, like a drowning man swept away by waves. He was overwhelmed by raging torrents. From these things no one can free himself. From these things only the Lord delivers and saves.
David's winning weapon is faith that is transformed into heartfelt prayer to be raised to the Lord, because only the Lord could help him, and it is to Him that David cries out in his distress. This is what David does: in his distress, he does not lose himself, he does not lose his faith, he remains whole. He turns his faith into prayer. He invokes the Lord. He cries out to Him. He asks Him for help and succour. God hears David's voice, hears it from his temple. His cry reaches him.
God becomes angry because He sees His elect in danger. The Lord's anger produces an upheaval of the whole earth. The earth trembles and shakes. The foundations of the mountains shake. It is as if a mighty earthquake turned the globe upside down. The spiritual fact is translated into such a profound upheaval of nature that one has the impression that creation itself is about to cease to exist. In this catastrophe that strikes terror, the righteous is rescued.
The Lord frees David because he loves him. Here is the secret of the answer to the prayer: the Lord loves David (v. 20). The Lord loves David because David loves the Lord. Prayer is a relationship of love between man and God. David invokes God's love. God's love responds and draws him to safety.
"Wholesome have I been with him, and I have guarded myself from guilt" (v. 24). David's conscience testifies for him. David prayed with an upright conscience, with a pure heart. This he says not only to God, but to every man. Everyone must know that the righteous is truly righteous. The world must know the integrity of God's children. We have a duty to confess it. It is on integrity that truly human relationships can be built. Without integrity, every relationship is tightened on falsehood and lies.
"The way of God is straight, the word of the Lord is tried by fire" (v. 31). What is the secret because God is with David? It is David's abiding in the Word of God. David has a certainty: the way indicated by the Word of God is straight. One only has to follow it. This certainty is lacking in the hearts of many today. Many do not believe in the purity of God's Word. Many think that it is now outdated. Modernity cannot stand under the Word of God.
"For who is God, if not the Lord? Or who is rock, if not our God?" Now David professes his faith in the Lord for all to know. Is there any other God but the Lord? God alone is the Lord. God alone is the rock of salvation. To seek another God is idolatry. This profession of faith must always be made aloud (remember the 'Creed'). Convinced people are needed. A faith hidden in the heart is dead. A seed placed in the ground springs up and reveals the nature of the tree. Faith that is in the heart must sprout up and reveal its nature of truth, holiness, righteousness, love and hope. A faith that does not reveal its nature is dead. It is a useless faith.
"He grants his king great victories; he shows himself faithful to his anointed, to David and his seed for ever" (v. 51). In this Psalm, David sees himself as the work of God's hands. That is why he blesses him, praises him, magnifies him. God's faithfulness and great favours for David do not end with David. God's faithfulness is for all his descendants. We know that David's descendants are Jesus Christ. With Jesus God is faithful for ever. With the other descendants, God will be faithful if they are faithful to Jesus Christ.
Here, then, the figure of David disappears to make way for that of the perfect king in whom the saving action that God offers the world is concentrated. In the light of this reinterpretation, the ode entered the Christian liturgy as a victory song of Christ, the 'son of David', over the forces of evil and as a hymn of the salvation he offered.
