'Day' in the Bible

Moreover, we possess the prophetic word as an altogether reliable thing. You do well if you pay attention to this as you would to a light shining in a murky place, until the day dawns and the morning star rises in your hearts.

(for while he lived among them day after day, that righteous man was tormented in his righteous soul by the lawless deeds he saw and heard)

-- if so, then the Lord knows how to rescue the godly from their trials, and to reserve the unrighteous for punishment at the day of judgment,

But by the same word the present heavens and earth have been reserved for fire, by being kept for the day of judgment and destruction of the ungodly.

Now, dear friends, do not let this one thing escape your notice, that a single day is like a thousand years with the Lord and a thousand years are like a single day.

But the day of the Lord will come like a thief; when it comes, the heavens will disappear with a horrific noise, and the celestial bodies will melt away in a blaze, and the earth and every deed done on it will be laid bare.

while waiting for and hastening the coming of the day of God? Because of this day, the heavens will be burned up and dissolve, and the celestial bodies will melt away in a blaze!

But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the honor both now and on that eternal day.
