Acts 20:29-32

²⁹I know that, after my departure, merciless wolves will get in amongst you, who will not spare the flock;

³⁰and from amongst yourselves, too, people will arise, who will teach perversions of truth, so as to draw away the disciples after them.

³¹Therefore, be on your guard, remembering how for three years, night and day, I never ceased, even with tears, to warn each one of you.

³²And now I commend you to the Lord and to the message of his love — a message which has the power to build up your characters, and to give you your place amongst all those who have become Christ's people.
