'Appearing' in the Bible

but has now been revealed by the appearing of our Savior, Christ Jesus, who abolished death, and brought life and immortality to light through the Good News.

I command you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at his appearing and his Kingdom:

From now on, there is stored up for me the crown of righteousness, which the Lord, the righteous judge, will give to me on that day; and not to me only, but also to all those who have loved his appearing.
