Day unto day utters speech, and night unto night shows knowledge.
Read Chapter 19
Augustine of Hippo
AD 430
3. "Day unto day uttereth word" (ver. 2). To the spiritual the Spirit giveth out the fulness of the unchangeable Wisdom of God, the Word which in the beginning is God with God.

Utterth, with great force and abundance, eructat.
