5. Modern Connections: Verses 13-16 align remarkably with modern embryology and genetics (DNA), illustrating the divine design of life at a microscopic level.
6. Practical Applications: 1. Finding comfort in God's presence; 2. Recognizing the sanctity of human life; 3. Standing for righteousness; 4. Inviting God's internal examination.
7. Further Study Recommendations: Charles Spurgeon's "Treasury of David" for devotional depth, and the "Word Biblical Commentary" for structural analysis.

5. Contemp.: Warren Wiersbe emphasizes this passage firmly establishes the dignity and sanctity of unborn life.

4. Classic: Calvin explains this as "ardent zeal," showing the believer's refusal to compromise with blasphemers.
5. Contemp.: John Stott notes that while Christians love enemies, the core spirit here is "absolute loyalty to God" over sinful values.
6. Scientific: A sense of justice is hardwired; this addresses the cognitive dissonance felt when witnessing unpunished evil.
7. Cross-Ref: Psalm 5:4 (You are not a God who takes pleasure in wickedness).
