Acts 20:27 Meaning

25And now, behold, I know that ye all, among whom I have gone preaching the kingdom of God, shall see my face no more.

26Wherefore I take you to record this day, that I am pure from the blood of all men.

27For I have not shunned to declare unto you all the counsel of God.

28Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.

29For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
