'Appearing' in the Bible

but hath now been manifested by the appearing of our Saviour Christ Jesus, who abolished death, and brought life and immortality to light through the gospel,

I charge thee in the sight of God, and of Christ Jesus, who shall judge the living and the dead, and by his appearing and his kingdom:

henceforth there is laid up for me the crown of righteousness, which the Lord, the righteous judge, shall give to me at that day; and not to me only, but also to all them that have loved his appearing.
