Acts 20
28 Ref Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
29 Ref For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
30 Ref Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
