This is an English translation of Martin Luther's lectures on Genesis, chapters 45 through 50. It is translated by Paul D. Pahl, professor of church history at Concordia Seminary, Adelaide. It contains an index to Luther's works, and a Scripture index. This English edition is intended primarily for the reader whose knowledge of late medieval Latin and sixteenth-century German is too small to permit him to work with Luther in the original languages. Based on the Weimar edition, its texts and helps have formed a basis for this edition, although in certain cases the translator has felt constrained to depart from its readings and findings. Where literal accuracy and clarity have conflicted, clarity has been chosen, so that sometimes paraphrase seemed more faithful than literal fidelity.
