Smith's Bible Dictionary [1]

Ru'mah. (High). Mentioned once only -  2 Kings 23:36. It has been conjectured to be the same place as Arumah ,  Judges 9:41, which was apparently near Shechem. It is more probable that it is identical with Dumah, 2 .  Joshua 15:52. See Arumah; Dumah, 2 .

Hastings' Dictionary of the Bible [2]

RUMAH . The home of Pedaiah, the maternal grandfather of Jehoiakim (  2 Kings 23:36 ). Josephus ( Ant. X. v. 2) reads Abouma , no doubt a scribal error for Arouma , which may be the Arumah of   Judges 9:41 near Shechem. There was another Rumah in Galilee (Jos [Note: Josephus.] BJ III. vii. 21), perhaps the modern Rumeh near Nazareth; and Pedaiah may have been a Galilæan.

Fausset's Bible Dictionary [3]

 2 Kings 23:36. Birthplace of Pedaiah, father of Zebudah ( 2 Kings 23:36). Probably Dumah , a town in the mountains of Judah near Hebron ( Joshua 15:52).

International Standard Bible Encyclopedia [7]

rōō´ma ( רוּמה , rūmāh  ; Codex Vaticanus Ῥουμά , Rhoumá  ; Codex Alexandrinus Ῥυμά , Rhumá ): To this place belonged Pedaiah whose daughter Zebudah (the Revised Version (British and American) "Zebidah") entered the harem of Josiah, king of Judah, and became the mother of Jehoiakim (  2 Kings 23:36 ). Josephus ( Ant. , X, v, 2) calls the place Abouma, but this is an obvious clerical error for Arouma. This suggests a possible identification with Arumah ( Judges 9:41 ), which lay not far from Shechem. Another possible identification is with the Rumah mentioned by Josephus ( BJ , III, vii, 21) in Galilee (compare Neubauer, Geog. du Talmud , 203), which may be identical with the modern Khirbet Rūmeh , about 3 miles North of Ṣeffūriyeh . Some, however, would identify Rumah with Dumah of  Joshua 15:52 , where the substitution of "r" for "d" is supported by the Septuagint ( Rheuma ), possibly represented by the modern Dōmeh , about 13 miles Southeast of Beit Jibrı̄n . This of course was in the territory of Judah, and no question of jus connubium is involved, such as might arise in the case of a Galilean site.

(Heb. Rumah', יוּמָה , High ; Sept. ῾Ρουμά ; Vulg. Ruma ; Josephus, Ἀβούμα , Ant. 10, 5, 2), a city named only in  2 Kings 23:36 as the home of Pedaiah, father of Jehoiakim's mother, Zebudah. It is probably the same with Arumah ( Judges 9:41), which is identified by Schwarz ( Palest. p. 158) with the modern Ramin, two miles west of Samaria. (See Arumah). Josephus mentions a Rumash in Galilee (War , 2, 7, 21). Others with less probability regard this as identical with Dumah , one of the towns in the mountains of Judah, near Hebron ( Joshua 15:52), not far distant from Libnah, the native town of another of Josiah's wives.
