'Ministers' in the Bible

Also we inform you, as regards all the priests and Levites, singers, doorkeepers, Nethinim, and ministers of this house of God, it shall not be lawful to impose tribute, tax, and toll upon them.

And I gave them a commission to Iddo the chief, at the place Casiphia, and I put words in their mouths to say to Iddo and his brethren the Nethinim, at the place Casiphia, that they should bring to us ministers for the house of our God.
