'Day' in the Bible

I was in the Spirit on the Lord's Day when I heard behind me a loud voice like a trumpet,

Each one of the four living creatures had six wings and was full of eyes all around and inside. They never rest day or night, saying: "Holy Holy Holy is the Lord God, the All-Powerful, Who was and who is, and who is still to come!"

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

For this reason they are before the throne of God, and they serve him day and night in his temple, and the one seated on the throne will shelter them.

Then the fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of them were darkened. And there was no light for a third of the day and for a third of the night likewise.

Then the four angels who had been prepared for this hour, day, month, and year were set free to kill a third of humanity.

Then I heard a loud voice in heaven saying, "The salvation and the power and the kingdom of our God, and the ruling authority of his Christ, have now come, because the accuser of our brothers and sisters, the one who accuses them day and night before our God, has been thrown down.

And the smoke from their torture will go up forever and ever, and those who worship the beast and his image will have no rest day or night, along with anyone who receives the mark of his name."

For they are the spirits of the demons performing signs who go out to the kings of the earth to bring them together for the battle that will take place on the great day of God, the All-Powerful.

For this reason, she will experience her plagues in a single day: disease, mourning, and famine, and she will be burned down with fire, because the Lord God who judges her is powerful!"

And the devil who deceived them was thrown into the lake of fire and sulfur, where the beast and the false prophet are too, and they will be tormented there day and night forever and ever.

Its gates will never be closed during the day (and there will be no night there).
