Can A Bishop Practice Polygamy?

What is a Bishop? 
A bishop (English derivation from the New Testament of the Bible Greek ἐπίσκοπος,epískopos, "OVERSEER","guardian") is an ordained, consecrated, or appointed member of the clergy who is generally entrusted with a position of authority and oversight, a leader.

 Ex:25 For ye were as sheep going astray; but are now returned unto the shepherd  and bishop of your souls.
1 Timothy 3:1-3 3 
This is a true saying, if a man desire the office of a bishop, he desireth a good work. 
2 A bishop then must be blameless, the husband of ONE wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; 
3 Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous 

 Titus 1:6-8 
6 If any be blameless, the husband of ONE wife, having faithful children not accused of riot or unruly.
7 For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre; 
8 But a lover of hospitality, a lover of good men, sober, just, holy, temperate; 

Conclusion

It is important that a Bishop have one wife, because he is to lead by example in holiness. When one leads by example, they set a pattern and a standard that others should follow...
