'Departure' in the Bible

who appeared in glory [and] were speaking [about] his departure which he was about to fulfill in Jerusalem.

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

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

And I will also make every effort [that] you are able at any time, after my departure, {to recall these things to mind}.
