Matthew Henry's Commentary

Matthew Henry emphasizes the seamless connection between God’s creation and His everlasting mercy. He notes that the mention of the moon and stars symbolizes God’s faithfulness and the way in which He governs the universe. Each element in the created order serves a purpose, reflecting God's intricate design and benevolent oversight.

Henry draws attention to the significance of night and its associated challenges, contrasting it with God's ongoing mercy. He teaches that the moon gives light in the dark, which might reflect God's guidance and support even during difficult times. The verse serves to assure believers of God's constant presence and care throughout all seasons of life.

Albert Barnes' Notes on the Bible

Albert Barnes elaborates on the role of the moon and stars in the context of ancient Hebrew culture, noting their importance in navigation and agriculture. He describes how these celestial bodies not only provide physical light but also symbolize hope and direction for the faithful. Barnes points out that the phrase "for his mercy endureth forever" serves as a refrain throughout the psalm, emphasizing a core message of God’s eternal steadfastness.

Barnes suggests that this enduring mercy manifests through God's regular renewals of day and night, underscoring that each phase of the heavens reflects His control over creation. The moon by night, while it may be associated with darkness, exemplifies that God’s light—symbolizing His mercy—never fails, even when it may be less visible to the human eye.

Adam Clarke's Commentary

Adam Clarke provides a theological reflection on the cosmic role of the moon and stars as indicators of God's omnipotence. He makes a theological distinction between creation's physical attributes and divine mercy, emphasizing that while the moon and stars shine in the night, they are reminders of the greater mercy and light that comes from God alone. Clarke asserts that these elements illustrate God's reliable blessings that accompany nights of darkness.

Clarke also highlights the poetic structure of this psalm, noting how the repetition serves as a liturgical device, urging Israel and its readers to reflect on God's enduring mercy. He stresses that in both creation’s governance and His covenant relationship, God’s fidelity remains unbroken—affirming the belief that His love sustains all of creation, including each individual believer.
