'Day' in the Bible

I constantly thank my God whom I serve with a clear conscience, as my ancestors did when I remember you in my prayers night and day,

That is why I suffer as I do. However, I am not ashamed, for I know the one in whom I have put my trust, and I'm convinced that he is able to protect what he has entrusted to me until the day that he comes.

May the Lord grant that he finds mercy on the day he comes again. You know very well how much he assisted me in Ephesus.

The victor's crown of righteousness is now waiting for me, which the Lord, the righteous Judge, will give to me on the day that he comes, and not only to me but also to all who eagerly wait for his appearing.
