Caspiane or Kaspiane (Greek: Κασπιανή, Armenian: Կասպք Kaspkʿ) was the land populated by the tribe of Caspians, after whom it received its name.
[1] It roughly corresponded to the modern Mugan plain and Qaradagh regions.
Some biblical scholars had suggested that Kasiphia from the Book of Ezra is Caspiane, due to phonetic resemblance.
Ezra, who saw there were not many Levites for recreating the Hebrew worship, asked Iddo, who led the Israelites (it is not specified whether they were from the Northern Kingdom of Israel or the Kingdom of Judah) and Canaanite servants who were exiled alongside them, for reinforcement.
Iddo sent him 38 Levites and 220 Canaanite Servants (who were descendants of those King David enslaved) to join the Jews who were returning to Zion.
