Acts 20:29-32

²⁹Because I know this, that after my departure savage wolves will come in among you, not sparing the flock.

³⁰Yes, men will rise up from among you yourselves, speaking distorted things, to draw away the disciples after them.

³¹Therefore be alert, remembering that during three years, night and day, I never stopped admonishing each one, with tears.

³²“And so now, brothers, I entrust you to God and to the Word of His grace, which is able to build you up and to give you an inheritance among all those who have been sanctified.
