'Crowing' in the Bible

when the doors (lips) are shut in the streets and the sound of the grinding [of the teeth] is low, and one rises at the sound of a bird and the crowing of a rooster, and all the daughters of music (voice, ears) sing softly.

Therefore be alert, since you don’t know when the master of the house is coming—whether in the evening or at midnight or at the crowing of the rooster or early in the morning.
