Night

Dictionary of Biblical Words:

An expression figuratively applied to the present time of Christ’s absence, who is the Light and Sun of the new creation. The Christian is not of the night, although in the night (1 Thess. 5), but is of the day—hence is to walk and watch until the Lord’s return, as the bright and morning Star, before He rises as the Sun of righteousness, to usher in the millennial day. Individually, during the night, the believer is to shine like a star; collectively, the church may be compared to the moon, showing with a reflected light the beauties of her absent Lord.

Boyd’s Bible Dictionary:

The Hebrew day, from sunset to sunset, embraced the entire night

(Gen. 1:5⁵And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day. (Genesis 1:5)). Death (John 9:4⁴I must work the works of him that sent me, while it is day: the night cometh, when no man can work. (John 9:4)); sin (1 Thess. 5.5); sorrow, sin, and death (Rev. 21:25; 22:5²⁵And the gates of it shall not be shut at all by day: for there shall be no night there. (Revelation 21:25)
⁵And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever. (Revelation 22:5)).

Concise Bible Dictionary:

Used symbolically for:

1. Death, a time “when no man can work” (John 9:4⁴I must work the works of him that sent me, while it is day: the night cometh, when no man can work. (John 9:4)).

2. The moral darkness of the world, in which men sleep and are drunken (1 Thess. 5:7⁷For they that sleep sleep in the night; and they that be drunken are drunken in the night. (1 Thessalonians 5:7)).

3. The period of Christ’s rejection, which is far spent, and the “day” at hand (Rom. 13:12¹²The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armor of light. (Romans 13:12)). There will be no night of moral or spiritual darkness in the heavenly Jerusalem (Rev. 21:25²⁵And the gates of it shall not be shut at all by day: for there shall be no night there. (Revelation 21:25); Rev. 22:5⁵And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever. (Revelation 22:5)).
