Psalm 18:3-4 — day to day utters speech; night announces knowledge

“Day to day utters speech, and night to night announces knowledge. There are no speeches, nor words, whose voices are not heard” (Psalm 18:3-4).

Of Eusebius. Night and day, being appointed measures of the seasonal withdrawal, both according to decrease and increase, and keeping the analogy toward one another through all, proclaim through the works the one who distinguished both; for the perpetual and unconfused is not in things according to chance, but a harmony, offspring of wisdom. And the voices of their words are not of those not heard; for everywhere of the inhabited world they are heard through the sight, both of heavens being seen, and of night and day.

And Paul used these sayings upon the apostles; therefore he also spoke indefinitely, but not as he is accustomed on the preceding to say: “Isaiah cries over Israel.” And again: “As Isaiah has said before.” And again: “As it is written.” And again: “For the Scripture says.” And Symmachus rendered more clearly: “And night to night announces knowledge, not with sayings, nor with words, whose voices are not heard, but into all the earth went out a sound.” Or according to Aquila: “Their rule, for they send forth neither word nor voice; but indicating the rule and their own order, they call all earth and sea to the divine hymnody.”

And the day of the resurrection utters speech to the day of the cross, how the one crucified in that day here rose as God, and raised the dead. And the night that happened before the cross announces such knowledge to the night of Christ’s betrayal, how in that night fearing and praying, and later also being handed over, in this day he is master of the elements, so as even to bring on night in the middle of the day, he has been shown.
