Romans 13:6 - Joseph Benson’s Commentary on the Old and New Testaments

For this cause pay ye tribute also Not only in token of the duty and subjection you owe them, but because they are the ministers (officers) of God For the public good; attending continually on this very thing Giving the whole of their time, care, and labour to it. “The phrase, λειτουργοι Θεου, rendered ministers of God, signifies ministers appointed by God in behalf of the people. The thing to which the magistrates attend, or ought to attend continually, is the good of the people; which they should promote by restraining evil-doers, distributing justice, and repelling the attacks of foreign enemies. Now these things they cannot do, unless taxes are paid to them.”
