IDDO (ĭd'ō). The English equivalent of several Jewish names:
1. Hebrew yiddô. (a) Son of Zechariah and a captain under David of the half-tribe of Manasseh east of the Jordan (1Chr.27.21). (b) One who had taken a foreign wife at the time of Ezra (Ezra.10.43 asv; niv “Jaddai”).
2. Hebrew ’iddô. The head of a community of temple servants (kjv Nethinim) at Casiphia; they provided Ezra with Levites and temple servants (Ezra.8.17).
IDDO ĭd’ ō. 1. (עִדֹּ֖א, opportune, timely, 1 Kings 4:14): father of one of Solomon’s twelve district officers, named Abinadab.
2. (יִדֹּ֖ו, beloved favorite, 1 Chron 6:21). A Levite from the family of Gershom, who is presumably the same one referred to in v. 41 as Adaiah (עֲדָיָֽה). He is the son of Joah and the father of Zerah.
3. A prince appointed by David over the half-tribe of Manasseh in Gilead, the son of Zechariah (1 Chron 27:21).
4. One of the men guilty of taking a foreigner for a wife and who was compelled by Ezra to release her (1 Esd 9:35; Jaddai, Ezra 10:43).
5. (עִדֹּ֥ו or עִדּוֹא). A prophet and seer who served as the source for the Chronicler’s material on Solomon (2 Chron 9:29), Rehoboam (2 Chron 12:15), and Abijah (2 Chron 13:22). In 2 Chronicles 9:29 the Kethiv is יֶעְדִּי and the Qere is יֶעְדֹּ֣ו.
6. (אִדֹּ֣ו, noble, mighty [?]). The head of a group of Levites at Casiphia who provided Ezra with Levites and Nethinim to be servants in the Temple upon their return to Jerusalem after the Exile (Ezra 8:17; 1 Esd 8:45, 46).
7. (עֲדָיָא, H6345, Qere of Neh 12:16; עִדֹּ֥וא, Kethib of Neh 12:16). One of the priestly families who returned with Zerubbabel to Jerusalem. (Neh 12:4, 16). Because 12:16 makes him the father of Zechariah, many connect this Iddo with 8 below.
8. (עִדֹּ֥וא), the grandfather of Zechariah the prophet (Zech 1:1, 7; Ezra 5:1; 6:14). If the Heb. accents connecting the words “Iddo the prophet” (cf. LXX and Vulgate) are accepted, then this is a different Iddo from 7 above.
International Standard Bible Encyclopedia (1915)
(1) (’iddo (?[~’adhadh, "to be strong"), "hap," "happy" (?), Ezr 8:17): The "chief at the place Casiphia," who provided Ezra with Levites and Nethinim, the head of the Levitical body or school, said to be one of the Nethinim or temple slaves, but perhaps an "and" has slipped out, and it should read: "his brethren and the Nethinim." 1 Esdras 8:45,46 has "Loddeus (the "Saddeus"), the captain who was in the place of the treasury," keceph meaning silver. Septuagint has "in the place of the silver (en argurio tou topou) .... to his brethren and to the treasurers."
(2) (yiddo, "beloved," or "loving," 1Ch 27:21): Son of Zechariah, and captain of the half-tribe of Manasseh in Gilead, under David.
(3) (yiddo, "beloved," or "loving," Ezr 10:43): One of those who had taken foreign wives. Another reading is Jaddai, the King James Version "Jadau." In 1 Esdras 9:35 "Edos" (the King James Version "Edes").
(4) (`iddo’, "timely," 1Ki 4:14): Father of Abinadab, Solomon’s commissary in Mahanaim in Gilead.
(5) (yiddo, "beloved," or "loving," 1Ch 6:21): A Gershomite Levite, son of Joah, called Adaiah in verse 41; ancestor of Asaph.
(6) (ye`do (Kethibh ye`di), or `iddo, "decked," "adorned"): Seer (chozeh) and prophet (nabhi), the Chronicler’s "source" for the reign of Solomon (2Ch 9:29): "The visions of Iddo the seer concerning Jeroboam the son of Nebat"; and for the reign of Rehoboam (2Ch 12:15): "The histories of Iddo (`iddo) the seer, after the manner of (or, "in reckoning") genealogies"; and for the reign of Abijah (2Ch 13:22): "The commentary (midhrash) of the prophet Iddo" (`iddo). He may have been the prophet who denounced Jeroboam (1Ki 13), who is called by Josephus and Jerome Jadon, or Jaddo. Jerome makes Iddo and Oded the same.
(7) (`iddo, "timely," Zec 1:1): Grandfather (father, according to Ezra) of the prophet, Zechariah. See also Zec 1:7; Ezr 5:1; 6:14 (`iddo’). In 1 Esdras 6:1, "Addo."
