'Night' in the Bible

For you remember, brothers, our labor and hardship: working by night and day in order not to be a burden to any of you, we proclaimed to you the gospel of God.

night and day praying beyond all measure that [we] may see your face and complete what is lacking in your faith?

for [you] yourselves well know that the day of the Lord is coming in the [same] way as a thief in the night.

for you are all sons of light and sons of day. We are not of the night nor of darkness.

For those who sleep, sleep at night, and those who get drunk, are drunk at night.
