Acts 20:25-31

²⁵And now behold, I know that ye all, among whom I have gone preaching the kingdom of God, will see my face no more.

²⁶Wherefore I call you to witness 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 will enter in among you, not sparing the flock.

³⁰Also from your own selves will men arise, speaking perverse things, to draw away disciples after them.

³¹Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
