Acts 20:28-31

Wesley(i) 28 Take heed therefore to yourselves and to the whole flock, over which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. 29 For I know this, that after my departure grievous wolves will enter in among you, not sparing the flock. 30 Yea, from among yourselves men will arise, speaking perverse things, to draw away disciples after them. 31 Therefore watch, remembering that for three years, I ceased not to warn every one, night and day, with tears.
