'Dawn' in the Bible

And as the dawn came up the angels urged Lot saying, "Get up, take your wife and your two daughters {who are staying with you}, lest you be destroyed with the punishment of the city."

And Jacob remained alone, and a man wrestled with him until the breaking of the dawn.

Then he said, "Let me go, for dawn is breaking." But he answered, "I will not let you go unless you bless me."
