'Work' in the Bible

And King Herod heard [it], because his name had become known. And they were saying, "John, the one who baptizes, has been raised from the dead, and because of this these miraculous powers are at work in him."

It is like a man away on a journey, who left his house and gave his slaves authority--to each one his work--and to the doorkeeper he gave orders that he should be on the alert.
