'Day' in the Bible

I came to be in the Spirit on the Day of the Lord, when I heard a loud voice behind me like a trumpet,

Each of the four living creatures had six wings and were full of eyes inside and out. Without stopping day or night they were saying, "Holy, holy, holy is the Lord God Almighty, who was, who is, and who is coming."

For the great day of their wrath has come, and who is able to endure it?"

Then he told me, "These are the people who are coming out of the terrible suffering. They have washed their robes and made them white in the blood of the lamb. That is why: "They are in front of the throne of God and worship him night and day in his Temple. The one who sits on the throne will shelter them.

When the fourth angel blew his trumpet, one-third of the sun, one-third of the moon, and one-third of the stars were struck so that one-third of them turned dark. One-third of the day was kept from having light, as was the night.

So the four angels who were ready for that hour, day, month, and year were released to kill one-third of humanity.

Then I heard a loud voice in heaven say, "Now the salvation, the power, the kingdom of our God, and the authority of his Messiah have come. For the one who accuses our brothers, who accuses them day and night in the presence of our God, has been thrown out.

The smoke from their torture goes up forever and ever. There is no rest day or night for those who worship the beast and its image or for anyone who receives the mark of its name."

They are demonic spirits that perform signs. They go to the kings of the whole earth and gather them for the war of the great Day of God Almighty.

For this reason, her diseases that result in death, misery, and famine will come in a single day. She will be burned up in a fire, because powerful is the Lord God who judges her."

and the Devil who deceived them was thrown into the lake of fire and sulfur, where the beast and the false prophet were. They will be tortured day and night forever and ever.

Its gates will never be shut at the end of the day because there will be no night there.
