Twice the Song of Songs uses the phrase “breath of the day” to describe daybreak (2:17; 4:6).  Literally, this perhaps refers to the breezes of dawn (cf. Song of Songs 4:16).

More theologically, though, the coming of daybreak means new life and breath for the world.  As the sun causes the shadows of darkness to flee away, so the breezes breathe new life into the world.

Morning breaks, every morning, like the first morning.
