Acts 20:29-31 King James Version (KJV)
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.
Acts 20:29-31 New International Version (NIV)
29 I know that after I leave, savage wolves will come in among you and will not spare the flock. 30 Even from your own number men will arise and distort the truth in order to draw away disciples after them. 31 So be on your guard! Remember that for three years I never stopped warning each of you night and day with tears.
