Acts 20:28-31

MKJV(i) 28 Therefore take heed to yourselves, and to all the flock in which the Holy Spirit has made you overseers, to feed the church of God which He has purchased with His own blood. 29 For I know this, that after my departure grievous wolves shall enter in among you, not sparing the flock. 30 Also men shall arise from your own selves, speaking perverse things in order to draw disciples away after them. 31 Therefore watch and remember that for the time of three years I did not cease to warn everyone night and day with tears.
