After the exile in Babylon, the Judean community needed to confirm the legitimate ancestry of the priests. This genealogy of Kohath linked the ancestors from the Pentateuch to the high priests up to Judah's exile in 586 BC. Other records connected the priests after the exile to this lineage (see Ezra 3:2; 7:1–6; Haggai 1:1). Not all high priests were included in this list.
