'Revenue' in the Bible

Be it known now unto the king, that, if this city be builded, and the walls set up again, then will they not pay toll, tribute, and custom, and so thou shalt endamage the revenue of the kings.

Also, I issue a decree as to what you are to do for these Jewish elders for the rebuilding of this house of God: the full cost is to be paid to these people from the royal treasury out of the taxes of the provinces west of the River, and that without delay.
