Acts 20:28-31 CSB
Be on guard for yourselves and for all the flock of which the Holy Spirit has appointed you as overseers, to shepherd the church of God, which he purchased with his own blood. I know that after my departure savage wolves will come in among you, not sparing the flock. Men will rise up even from your own number and distort the truth to lure the disciples into following them. Therefore be on the alert, remembering that night and day for three years I never stopped warning each one of you with tears.
