Acts 20:26-29

26Therefore I testify to you this day, that I am pure from the blood of all men . 27For I have not shunned to declare to you all the counsel of God. 28Take heed therefore to yourselves, and to all the flock, over which the Holy Spirit hath made you overseers, to feed the church of God, which he hath purchased with his own blood. 29For I know this, that after my departure grievous wolves shall enter in among you, not sparing the flock.
