Acts 20:29-31

BRG Bible

²⁹ For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.

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

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