Acts 20:28-31

Twentieth_Century(i) 28 Be watchful over yourselves, and over the whole flock, of which the Holy Spirit has placed you in charge, to shepherd the Church of God, which he won for himself at the cost of his life. 29 I know that, after my departure, merciless wolves will get in among you, who will not spare the flock; 30 And from among yourselves, too, men will arise, who will teach perversions of truth, so as to draw away the disciples after them. 31 Therefore, be on your guard, remembering how for three years, night and day, I never ceased, even with tears, to warn each one of you.
