'Day and Night' in the Bible

And will not God execute the judgment of his elect, who cry day and night to him, even though he waits long on them?

and their design was made known to Saul. And they watched the gates day and night to kill him;

which our twelve tribes, serving God continually, day and night, hope to attain; of this hope, King Agrippa, I am accused by the Jews.

Therefore they are before the throne of God, and serve him day and night in his temple, and he that sits on the throne will dwell among them.

And I heard a loud voice in heaven saying, Now has come the salvation and power and kingdom of our God, and the power of his Christ, for the accuser of the brothers, that accused them day and night before God, has been cast [to the earth].

And the devil who deceived them was cast into the lake of fire and sulphur, where also the beast and the false prophet [were cast], and they shall be tormented day and night forever and ever.
