In this way corporeal beings are born, [re]born, annihilated,
Upon the arrival of night gone, Partha, emerge when day arrives.

The same multitude of beings come into existence again and again at the arrival of the day of Brahmaa, and they are annihilated, inevitably, at the arrival of Brahmaa's night.

Source: The Bhagavad-Gita: The Sacred Song

Again and again the day comes, and this host of beings is active; and again the night falls, O Partha, and they are helplessly dissolved.
