Sažetak The authors od this article are trying to present the importance of oral and written genealogies that were used for calculating chronology. We are told about discrepancies on some of the lists because it is possible that some names were purposely or by scribal error left out from the lists. In spite of these discrepancies these genealogies are the only existing documents that are at our disposal for calculating chronology. In addition, there are three version of these lists (Masoretic Texts, Septuagint, and Samaritan Pentateuch), and each list presents different years for the same individuals. To this respect the author presents all three lists with the same importance, but emphasis the idea that the Masoretic Texts are the most authentic.
