Ezra 7 Commentary discusses Ezra's genealogy and journey to Jerusalem. It provides context that Ezra was a descendant of Seraiah the high priest, though not his immediate son due to a 130 year gap. Scholars debate whether the king mentioned, Artaxerxes, refers to Artaxerxes I or II, with implications for the timeline. Ezra is described as a skilled scribe of the law of Moses who went to Jerusalem to teach God's statutes during the reign of the Persian king Artaxerxes.
