1 Timothy 3:4-7

one that ruleth well his own house, having his children in subjection with all gravity; (but if a man knoweth not how to rule his own house, how shall he take care of the church of God?) not a novice, lest being puffed up he fall into the condemnation of the devil. Moreover he must have good testimony from them that are without; lest he fall into reproach and the snare of the devil.
