'Day and Night' in the Bible

And the four living creatures, each one of them having six wings, are full of eyes around and within; and day and night they do not cease to say,“Holy, holy, holy is the Lord God, the Almighty, who was and who is and who is to come.”

For this reason, they are before the throne of God; and they serve Him day and night in His temple; and He who sits on the throne will spread His tabernacle over them.

Then 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, for the accuser of our brethren has been thrown down, he who accuses them before our God day and night.

And the smoke of their torment goes up forever and ever; they have no rest day and night, those who worship the beast and his image, and whoever receives the mark of his name.”

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