1 Timothy 3:8-13

v8-9: Deacons main work is to "take care of the temporal concerns of the church, such as the salaries of ministers and providing for the poor."  It is necessary that they have a good character because they are "entrusted with the church's money" and it would especially be bad if they are greedy for money because they might be "tempted to embezzle and convert to their own use what was intended for the public service."

v10-13: "People’s qualifications should be assessed before they are admitted into church office, or indeed before any trust is committed to them."  Prospective deacons should be tested for 'the soundness of their judgments, their zeal for Christ, and the blamelessness of their way of life."
