God's wisdom is clearly shown in many places:
It appears in the heavens (Psalm 19:1–4),
in nature (Psalm 19:4–6),
in his teachings (Psalm 19:7–11), and
in the life of the psalmist (Psalm 19:12–14)
Like Psalm 8, this hymn uses creation to lead people to reflect on God. It offers a calm moment after the intense prayers and victory songs in earlier psalms.
The psalm begins with creation as a source of wisdom. It then moves to God’s word as the perfect source of wisdom. Finally, it ends with the human need for redemption.
