Application and re-Interpretation of biblical traditions in the Book of Malachi. A traditio-historical study. Six passages in Malachi, together with the superscription (Mal 1:1) and the additions (Mal 3:22‑24), are analyzed. The creative use of the traditions is demonstrated, including the prophet's exegetical techniques. Lines of connections are detected between Malachi and legal texts (Leviticus and Deuteronomy), earlier prophetic words, Chronicles, and Wisdom literature. The author is Dr. Theol. and Associate Professor of Old Testament at Det teologiske Menighetsfakultet (The Norwegian Free Lutheran School of Theology), Oslo.
