Albert Barnes Commentary Ezra 1:8

"even those did Cyrus king of Persia bring forth by the hand of Mithredath the treasurer, and numbered them unto Sheshbazzar, the prince of Judah." — Ezra 1:8 (ASV)

Mithredath - Or, “Mithridates.” The occurrence of this name, which means “given by Mithra” or “dedicated to Mithra,” is an indication that the sun-worship of the Persians was at least as old as the time of Cyrus.

Sheshbazzar - i. e., Zerubbabel. On his royal descent, see 1 Chronicles 3:19 note.
