Towards the end of the 4th century - for the first time in the history of Latin-speaking Christianity - Jerome, the Father of the Church translated the writings of the Old Testament from the Hebrew, hebraica veritas. According to his own testimony he borrowed from the Septuagint and the hexaplaric translations (Aquila, Symmachus and Theodotion) and also allowed himself to be briefed by Jewish scholars on philological and exegetical traditions. Weigert compares the Latin text of the book of Deuteronomy to these sources as well as to more contemporary Jewish literature (Targums, Midrash) in order to reveal the principles that guided Jerome in his translations, as well as the sources on which he drew when tackling the hebraica veritas .
