As the Nazi’s purged the German universities of those who did not think like them, Karl Barth exhorted the students and preachers he left behind with some version of the following quote. (This one is found in Karl Barth’s Theological Exegesis: The Hermeneutical Principles of the Romerbrief Period by Richard E. Burnett).
Dear friends, who have listened to me, the main thing you have heard from me is dogmatics. Dogmatics is a high and steep art. I do not want to deny that, humanly as well, I strive after it with a certain love and desire. And I dare say that I have noticed that many of you have been excited about this subject matter as well. If this now for the moment has come to an end, accept this as a signal for you to temporarily begin anew your studies at a different place. Take now my last piece of advice: Exegesis, Exegesis, and once more, Exegesis! If I have become a dogmatician, it is because I long before have endeavored to carry on exegesis. Let the systematic art, which can also make one mad, rest a little and hold on to the Word, to the Scriptures, which is given to us and become perhaps less systematic and more biblical theologians. For then the systematic and dogmatic tasks will certainly be taken care of as well. That is what I wanted to say to you and in this way I wish to be you farewell.
