Acts 20:25-31

25And now, behold, I know that none of you among whom I have gone about proclaiming the kingdom will see my face again. 26Therefore I testify to you this day that I am innocent of the blood of all, 27for I did not shrink from declaring to you the whole counsel of God. 28Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood. 29I know that after my departure fierce wolves will come in among you, not sparing the flock; 30and from among your own selves will arise men speaking twisted things, to draw away the disciples after them. 31Therefore be alert, remembering that for three years I did not cease night or day to admonish every one with tears.
