Charles Ellicott Commentary Ezra 7:1

"Now after these things, in the reign of Artaxerxes king of Persia, Ezra the son of Seraiah, the son of Azariah, the son of Hilkiah," — Ezra 7:1 (ASV)

After these things. — Fifty-seven years after: this special phrase is used here alone. During the interval, we must place the events of the Book of Esther.

Ezra the son of Seraiah. — His lineage is given, as frequently in Scripture, compendiously, and according to the genealogical law which makes every ancestor a “father” and every descendant a “son.” We do not know the reason why certain names supplied in 1 Chronicles 6:0 are omitted here; but Seraiah is claimed as the father of Ezra because he was the eminent high priest who last ministered in Solomon’s Temple and was slain at Riblah (2 Kings 25:18). The links missing in the lineage are easily supplied.
