Acts 14:23 - And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.
1Timothy 3:8-13 - Deacons likewise must be dignified, not double-tongued, not addicted to much wine, not greedy for dishonest gain. They must hold the mystery of the faith with a clear conscience. And let them also be tested first; then let them serve as deacons if they prove themselves blameless. Their wives likewise must be dignified, not slanderers, but sober-minded, faithful in all things. Let deacons each be the husband of one wife, managing their children and their own households well.
