Psalm 51 — 53
The Saints Are Laughing (vv. 5–7) Verse 5 is the central verse of the psalm and marks the turning point in David's experience as he contemplated the wickedness of the human heart. He was confident that God would one day judge Saul, Doeg, and all who follow their evil philosophy of life. Note the powerful verbs: "break you down … snatch you up … tear you away … uproot you…." (NASB). (See Job 18 for a similar description.) The righteous would only see but not experience this devastation (91:8), and they would stand in awe of the holy wrath of God (40:3). Then they would laugh in derision at the humiliating fall of these pompous leaders (2:4). What Saul and Doeg did to the priestly community at Nob (1 Sam. 22:6ff.), the Lord would do to them, for sinners ultimately fall into the pits they dig for others (9:15; Prov. 26:24–28; 29:6).
David's hands, for it was David who ordered his death (2 Sam. 11:6ff.; see Ezek. 3:18–20; 18:13; Acts 20:26).
David was wealthy enough to bring many sacrifices to the Lord, but he knew that this would not please the Lord (50:8–15; see 1 Sam. 15:22) and that their blood could not wash away his sins. David wasn't denying the importance or the validity of the Jewish sacrificial system; he was affirming the importance of a repentant heart and a spirit yielded to the Lord (Isa. 57:15). God could not receive broken animals as sacrifices (Mal. 1:6–8), but He would receive a broken heart! Some students believe that verses 18–19 were added later to adapt this very personal psalm for corporate worship, but there's no reason why David could not have written these words. As king, he was certainly burdened for the welfare of Jerusalem and the kingdom, and he knew that his sins had weakened Israel's position among the nations (2 Sam. 12:14). David must have begun building and repairing the walls, otherwise Solomon couldn't have completed the work early in his reign (1 Kings 3:1). David destroyed much good when he sinned, but he also did much good during his lifetime and served the Lord faithfully.
The Faithful Are Serving (vv. 8–9) The contrast is clear: the wicked are like uprooted trees, but the godly are like flourishing olive trees that are fruitful and beautiful. Saul and Doeg would perish, rejected by the Lord, but David and his dynasty would be safe in the house of the Lord! It's possible that the tabernacle at Nob had olive trees growing around it, and David would have seen them. The olive tree lives for many years and keeps bearing fruit (1:3; 92:12–15; see Jer. 17:7–8, and note 37:35–36), and certainly David was a blessing to the nation while he lived and long after he died—and he is a blessing to us today. He trusted God's lovingkindness and the Lord did not fail him, and he never failed to give God the glory. The phrase "wait on thy name" (v. 9 kjv) means to hope and depend on the character of God as expressed in His great name. The psalm ends with David vowing to praise the Lord in the congregation as soon as God established him in his kingdom. The private victories God gives us should be announced publicly for the encouragement of God's people. Meanwhile, though evil may seem to triumph, we must continue to obey and serve the Lord and not get discouraged. The "last laugh" belongs to the Lord's people.
