'Task' in the Bible

I glorified you on earth by completing the task you gave me to do.

So when I have completed this task and have put my seal on this contribution of theirs, I will visit you on my way to Spain.

Who is Apollos, anyhow? Or who is Paul? They're merely servants through whom you came to believe, as the Lord gave to each of us his task.

This is a trustworthy saying: The one who would an elder be, a noble task desires he.
