'Day' in the Bible

And we have the word of prophecy made more sure; whereunto ye do well that ye take heed, as unto a lamp shining in a dark place, until the day dawn, and the day-star arise in your hearts:

(for that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their lawless deeds):

the Lord knoweth how to deliver the godly out of temptation, and to keep the unrighteous under punishment unto the day of judgment;

and saying, Where is the promise of his coming? for, from the day that the fathers fell asleep, all things continue as they were from the beginning of the creation.

but the heavens that now are, and the earth, by the same word have been stored up for fire, being reserved against the day of judgment and destruction of ungodly men.

But forget not this one thing, beloved, that one day is with the Lord as a thousand years, and a thousand years as one day.

But the day of the Lord will come as a thief; in the which the heavens shall pass away with a great noise, and the elements shall be dissolved with fervent heat, and the earth and the works that are therein shall be burned up.

looking for and earnestly desiring the coming of the day of God, by reason of which the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
