'Day' in the Bible

and we possess [as] more reliable the prophetic word, to which you do well [if you] pay attention to [it] as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts,

(for that righteous man, [as he] lived among them day after day, was tormenting [his] righteous soul by the lawless deeds [he was] seeing and hearing),

[then] the Lord knows how to rescue the godly from trials and to reserve the unrighteous to be punished at the day of judgment,

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

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

But the day of the Lord will come like a thief, in which the heavens will disappear with a rushing noise, and the celestial bodies will be destroyed [by] being burned up, and the earth and the deeds [done] on it will be disclosed.

[while] waiting for and hastening the coming of the day of God, because of which the heavens will be destroyed [by] being burned up and the celestial bodies will melt [as they] are consumed by heat!

But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him [be] the glory, both now and to the day of eternity. Amen.
