'Custom' in the Bible

Now let it be known to the king, that if that city is rebuilt and the walls are finished, then they will not pay tax, custom, or toll, and the revenue of the kings will be diminished.

There have also been mighty kings over Jerusalem who have ruled over all the provinces west of the [Euphrates] River, and tax, custom, and toll were paid to them.

We also inform you that it is not authorized to impose tax, tribute, or toll on any of the priests, Levites, singers, doorkeepers, temple servants or other servants of this house of God.
