“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.”
King James Version (KJV)
13:4 The sword - The instrument of capital punishment, which God authorizes him to inflict.
Ro 13:4 For he is the minister of God to thee for good. The ruler, the guardian of order and the preserver of peace is, as a rule, a blessing. He beareth not the sword in vain. Not only did the magistrate wear the sword, but one was borne before him in public processions as an emblem of his right to use it in the interests of order and justice.
