'Night' in the Bible

Put haircloth round you and give yourselves to sorrow, you priests; give cries of grief, you servants of the altar: come in, and, clothed in haircloth, let the night go past, you servants of my God: for the meal offering and the drink offering have been kept back from the house of your God.

For a day of dark and deep shade is near, a day of cloud and black night: like a black cloud a great and strong people is covering the mountains; there has never been any like them and will not be after them again, from generation to generation.
