What's the difference between "errand" and "job"?
A "job" is normally a long-term position of work, whereas an errand is a short-term chore or a quick journey to get something. Jobs are also usually stationary, and don't involve going somewhere to get something done. Errands on the other hand usually involve going to some destination to complete a task. Ex: Painting the house is a week-long job. Ex: I have to go run an errand and pick up some groceries.
