I beg to differ, why do you think this is from Romans rather than Hebrews?

Ro:13:3:
For rulers are not a terror to good works,
but to the evil.
Wilt thou then not be afraid of the power?
do that which is good,
and thou shalt have praise of the same:
Ro:13:4:
For he is the minister of God to thee for good.
But if thou do that which is evil,
be afraid;
for he beareth not the sword in vain:
for he is the minister of God,
a revenger to execute wrath upon him that doeth evil.
Ro:13:5:
Wherefore ye must needs be subject,
not only for wrath,
but also for conscience sake.
Ro:13:6:
For for this cause pay ye tribute also:
for they are God's ministers,
attending continually upon this very thing.
Ro:13:7:
Render therefore to all their dues:
tribute to whom tribute is due;
custom to whom custom;
fear to whom fear;
honour to whom honour.
