Albert Barnes Commentary Ezra 4:9-10

"then [wrote] Rehum the chancellor, and Shimshai the scribe, and the rest of their companions, the Dinaites, and the Apharsathchites, the Tarpelites, the Apharsites, the Archevites, the Babylonians, the Shushanchites, the Dehaites, the Elamites, and the rest of the nations whom the great and noble Osnappar brought over, and set in the city of Samaria, and in the rest [of the country] beyond the River, and so forth." — Ezra 4:9-10 (ASV)

These verses form the superscription or address of the letter (Ezra 4:11, etc.) sent to Artaxerxes.

The Dinaites were probably colonists from Dayan, a country often mentioned in the Assyrian inscriptions as bordering on Cilicia and Cappadocia. No satisfactory explanation can be given for the name Apharsathchites (see Ezra 5:6 note).

The Tarpelites were colonists from the nation which the Assyrians called Tuplai, the Greeks “Tibareni,” and the Hebrews generally “Tubal.” (It is characteristic of the later Hebrew language to insert the letter “r” (resh) before labials. Compare Darmesek for Dammesek, 2 Chronicles 28:23 margin).

The Apharsites were probably “the Persians”; the Archevites, natives of Erech (Warka) (Genesis 10:10); the Susanchites, colonists from Shushan or Susa; the Dehavites, colonists from the Persian tribe of the Dai; and the Elamites, colonists from Elam or Elymais, the country of which Susa was the capital.

(Ezra 4:10) Asnappar was perhaps the official employed by Esarhaddon (Ezra 4:2) to settle the colonists in their new country.

On this side the river - literally, “beyond the river,” a phrase used of Palestine by Ezra, Nehemiah, and in the Book of Kings, as designating the region west of the Euphrates.

And at such a time - Rather, “and so forth.” The phrase is vague, nearly equivalent to the modern use of et cetera. It recurs in marginal references.
