over the which the Holy Ghost hath made you overseers,
to feed the church of God, which he hath purchased with his own blood.
enter in among you, not sparing the flock.
Also of your own selves shall men arise, speaking perverse things,
that by the space of three years
But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies,
even denying the Lord that bought them,
and bring upon themselves swift destruction.
2 Peter 2:1
