Matthew Henry on Ezra 7:1-10
Here is, I. Ezra's pedigree. He was one of the sons of Aaron, a priest. Him God chose to be an instrument of good to Israel, that he might put honour upon the priesthood, the glory of which had been much eclipsed by the captivity. He is said to be the son of Seraiah, that Seraiah, as is supposed, whom the king of Babylon put to death when he sacked Jerusalem, Kg2 25:18, Kg2 25:21.

See on Ezr 8:24-32 (note).
John Gill on Ezra 7:8
