'Night' in the Bible

who is going before you in the way to search out to you a place for your encamping, in fire by night, to shew you in the way in which ye go, and in a cloud by day.

Observe the month of Abib -- and thou hast made a passover to Jehovah thy God, for in the month of Abib hath Jehovah thy God brought thee out of Egypt by night;

When there is in thee a man who is not clean, from an accident at night -- then he hath gone out unto the outside of the camp -- he doth not come in unto the midst of the camp --

and thy life hath been hanging in suspense before thee, and thou hast been afraid by night and by day, and dost not believe in thy life;
