Day unto day uttereth speech, and night unto night sheweth knowledge. Day unto day uttereth speech - Each day is represented as teaching another relative to some new excellence discovered in these manifold works of God. The nights also, by the same figure, are represented as giving information to each other of the increase of knowledge already gained.
"The labors of these our instructers know no intermission; but they continue incessantly to lecture us in the science of Divine wisdom. There is one glory of the sun, which shines forth by day; and there are other glories of the moon and of the stars, which become visible by night. And because day and night interchangeably divide the world between them, they are therefore represented as transmitting, in succession, each to other, the task enjoined them, like the two parts of a choir, chanting forth alternately the praises ot God." - Bisbop Horne.
