2 Thessalonians 3:8
nor did we eat anyone’s food without paying for it. On the contrary, we worked night and day, laboring and toiling so that we would not be a burden to any of you
The Apostles get money from someone as their boss as a salary for their night and day work, laboring and toiling, then they use the money to pay their food.
So the question is :
what kind of work those Apostles do night and day in order to get money?
to whom (who is the boss) do they work night and day ?
