'Night' in the Bible

{who goes} {before you} on your way, seeking a place for your encampment, in fire at night and in a cloud by day, to show you the way that {you should go}.

"Observe the month of Abib, and you shall keep [the] Passover to Yahweh your God, for in the month of Abib Yahweh your God brought you out from Egypt [by] night.

"If [there] is among you a man that is not clean because of a seminal emission {during the night}, he shall go outside the camp; he shall not come within the camp.

And {your life shall hang in doubt before you}, and you shall be startled night and day, and you shall not be confident of your life.
