I have seen a number of pastors and their wives implement the position of the armour bear. These people stand guard for them, run errands, pray for them, provide a spiritual barrier between them and the devils tactics sent from outsiders, prepare meals and drinks, wipe sweat, pack luggages for trips etc.

Is this position biblical and necessary? What does the scripture say about this? Or do we see this as an "errand boy/girl for the pastor?
