'Working' in the Bible

The coming of the lawless one is based on Satan’s working, with all kinds of false miracles, signs, and wonders,

we did not eat anyone’s food free of charge; instead, we labored and struggled, working night and day, so that we would not be a burden to any of you.

For we hear that there are some among you who walk irresponsibly, not working at all, but interfering with the work of others.

Now we command and exhort such people by the Lord Jesus Christ that quietly working, they may eat their own food.
