what understanding of the cosmos shaped this ancient hebrew perspective on creation's 'speech'?

Adds the setting and its conversation across both testaments.

Psalm 19:1-4

“The heavens declare the glory of God. The expanse shows his handiwork. Day after day they pour forth speech, and night after night they display knowledge. There is no speech nor language. Their voice is not heard. Their message goes out through all the earth, and their words to the end of the world. In them he has set a tent for the sun,”

This psalm, attributed to David, celebrates the glory of God revealed in both creation and the Law. These opening verses describe how the natural world around us, particularly the sky, constantly communicates God's presence and power.

What does it mean for the natural world to 'speak' without words, and what kind of knowledge does it convey?

Then — the setting

This psalm originates from ancient Israel, likely during the monarchy (around 10th-6th centuries BCE). For the ancient Hebrews, the cosmos was generally understood as a structured, ordered creation by God, not a product of chance or the clash of primordial deities. They envisioned a three-tiered universe: the heavens above (God's dwelling, where the sun, moon, and stars resided), the earth below (a flat disc, often thought to be floating on water, with mountains, valleys, and seas), and Sheol or the underworld beneath. This order and regularity were seen as direct evidence of a divine architect and ruler.

Across the Testaments

The main passage is from the Old Testament, where the physical heavens are depicted as a primary means of revealing God's glory and knowledge. The New Testament affirms this understanding, often referencing the natural world as a testament to God's existence and attributes. Romans 1:20, for example, states that God's eternal power and divine nature are clearly perceived 'through what has been made.' While the Old Testament emphasizes the wonder of creation as a testament to God's power, the New Testament often frames this as a foundational truth that should lead people to seek God, and makes space for a more direct, personal revelation through Jesus Christ.
