Fausset's Bible Dictionary [1]

From Nebo, the idol; Zar , "prince"; and Adan or 'Adown , "lord" (Gesenius); but Furst, from Dana (Sanskrit), "cut off." "Captain of the guard," literally, "chief of the slaughterers"; next to the royal person ( 2 Kings 25:8-18;  Jeremiah 39:9-13). Assumed the chief command on arriving after the siege of Jerusalem. Directed what was to be done with the plunder and captives. (See Captivity .) Took the chief Jews for judgment to Nebuchadnezzar at Riblah. Visited Jerusalem four years later, and took away more captives ( Jeremiah 52:30). By Nebuchadnezzar's direction, Nebuzaradan "looked well to Jeremiah," gave him his choice of going to Babylon or staying, then sent him with victuals and a present, to be protected by Gedaliah the governor left over Judah, after having first told the Jews "Jehovah hath done according as He hath said, because ye have sinned against Jehovah" ( Jeremiah 39:11-14;  Jeremiah 40:2-5). The pagan knew, through Jeremiah, it was Jehovah's doing; compare the prophecy,  Deuteronomy 29:24-25. How humiliating to the Jews to be admonished of their sin by a Gentile ruler!

Cyclopedia of Biblical, Theological and Ecclesiastical Literature [10]

The name, like Nebuchadnezzar and Nebu-shasban, contains that of Nebo the Babylonian deity. The other portion of the word is less certain. Gesenius (Thes. page 839 b) translates by Mercurii dux doninus, taking the זִר as שִׂר , "prince," and אֲדָן as אָדוֹן "lord" Furst, on the other hand (Handb. s.v.), treats it as equivalent in meaning to the Hebrew Rab- Tabbachim, which usually follows it, and sometimes occurs by itself ( 2 Kings 25:18;  Jeremiah 40:2;  Jeremiah 40:5). To obtain this meaning he treats the first member as = Pers. sar, Sansc. ciro, "chief," as Gesenius; but compares the last member of the name to the Sansc. dana, from de, "to cut off." Gesenius also takes zaradan as identical with the first element in the name of Sardan-apalus. But this latter name is now explained by Sir H. Rawlinson as Assur-dan-i-pal (Rawlinson's Herod. 1:460).
