'Dawn' in the Bible

And as the dawn arose, the angels urged Lot, saying, Up, take thy wife and thy two daughters who are present, lest thou perish in the iniquity of the city.

And Jacob remained alone; and a man wrestled with him until the rising of the dawn.

And he said, Let me go, for the dawn ariseth. And he said, I will not let thee go except thou bless me.
