Acts 20:29-30; Acts 20:32; 2 Timothy 3:13-15
For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among all them which are sanctified.
But evil men and seducers shall wax worse and worse, deceiving, and being deceived.
But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;
And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
