5 Wherefore ye must needs be subject, not only for wrath, but also for conscience sake.
6 For for this cause pay ye tribute also: for they are God's ministers, attending continually upon this very thing.
7 Render therefore to all their dues: tribute to whom tribute is due; custom to whom custom; fear to whom fear; honour to whom honour.
