'Departure' in the Bible

who, appearing in glory, were speaking of His departure which He was about to accomplish at Jerusalem.

I know that after my departure savage wolves will come in among you, not sparing the flock;

As I urged you upon my departure for Macedonia, remain on at Ephesus so that you may instruct certain men not to teach strange doctrines,

For I am already being poured out as a drink offering, and the time of my departure has come.

And I will also be diligent that at any time after my departure you will be able to call these things to mind.
