This preface is found again word for word in Luther's "Auslegungen über den Propheten Habakuk", §§ 12-14, in this volume. The only difference is that there 8 12 begins: "So this Habakkuk is a prophet of comfort" etc. But here: "This Habakkuk is a prophet of comfort" etc. Therefore we leave out the preface here. It also appears twice in the Erlanger, vol. 42, p. 12 f. and vol. 63, p. 84 f.
*) This preface is found in Walch, in the Leipzig edition, vol. XII, p. 45 and in the Erlanger, vol. 63, p. 83.
