'Day and Night' in the Bible

And the four living creatures, {each one} of them, had six wings apiece, full of eyes around and inside, and they do not have rest day and night, saying, "Holy, holy, holy [is] the Lord God All-Powerful, the one who was and the one who is and the one who is coming!"

Because of this, they are before the throne of God, and they serve him day and night in his temple, and the one who is seated on the throne {will shelter} them.

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

And the smoke of their torture went up {forever and ever}, and those who worshiped the beast and his image did not have rest day and night, {along with anyone who received} the mark of his name.

And the devil who deceived them was thrown into the lake of fire and sulphur, where the beast and the false prophet also [are], and they will be tormented day and night {forever and ever}.
