Joshua 7:1BSB
The Israelites, however, acted unfaithfully regarding the things devoted to destruction. Achan son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, took some of what was set apart. So the anger of the LORD burned against the Israelites.
Joshua 7:1 identifies Achan as descending from Zerah of the tribe of Judah. First Chronicles 2:3 opens Judah's genealogy by naming Judah's sons Er, Onan, and Shelah, then proceeds to Perez and Zerah (born to Tamar), establishing the two major Judahite lines. Achan's lineage through Zerah is significant because it places him in the non-Davidic branch of Judah; the messianic line runs through Perez (1 Chr 2:5-15, culminating in David). This genealogical echo connects Achan's חֵרֶם (cherem) violation at Jericho to the broader Judahite family history, showing that covenantal unfaithfulness marked the Zerahite line while God's redemptive purposes advanced through Perez.
