A deacon must be the husband of but one wife, a good manager of his children and of his own household.

Philippians 1:1
Paul and Timothy, servants of Christ Jesus, To all the saints in Christ Jesus at Philippi, together with the overseers and deacons:

1 Timothy 3:2
An overseer, then, must be above reproach, the husband of but one wife, temperate, self-controlled, respectable, hospitable, able to teach,

1 Timothy 3:4
An overseer must manage his own household well and keep his children under control, with complete dignity.

1 Timothy 3:8
Deacons likewise must be dignified, not double-tongued or given to much wine or greedy for money.

Let the deacons be the husbands of one wife, ruling their children and their own houses well.
