Acts 20:28-31

Look after yourselves and everyone the Holy Spirit has placed in your care. Be like shepherds to God's church. It is the flock that he bought with the blood of his own Son. I know that after I am gone, others will come like fierce wolves to attack you. Some of your own people will tell lies to win over the Lord's followers. Be on your guard! Remember how day and night for three years I kept warning you with tears in my eyes.
