Ahi'ram. (Brother Of Height, Lofty). One of the sons of Benjamin, and ancestor of the Ahiramites  Numbers 26:38. In  Genesis 46:21, the name appears as "Ehi and Rosh." It is uncertain whether Ahiram is the same as Aher ,  1 Chronicles 7:12, or Aharah ,  1 Chronicles 8:1.

Hastings' Dictionary of the Bible [2]

AHIRAM . The eponym of a Benjamite family the Ahiramites,   Numbers 26:38 (P [Note: Priestly Narrative.] ). The name occurs in the corrupt forms Ehi in   Genesis 46:21 (P [Note: Priestly Narrative.] ), and Aharah in   1 Chronicles 8:1 .

International Standard Bible Encyclopedia [5]

a - hı̄´ram ( אחיום , 'ăḥı̄rām , "exalted brother," or "my brother is exalted"): A son of Benjamin. Mentioned third of the five in  Numbers 26:38 ,  Numbers 26:39 . In  1 Chronicles 8:1 five sons are likewise mentioned, being explicitly numbered; the third name, Aharah ( 'aḥraḥ ), is conjectured to be either a corruption of Ahiram or a different name for the same person. In  1 Chronicles 7:6 is a fuller list of Benjamite names, but it is fragmentary and not clear. In it occurs Aher ( 'aḥēr ), which may be either Ahiram or Aharah with the end of the word lost. In  Genesis 46:21 ten sons of Benjamin are mentioned, some being there counted as sons who, in the other lists, are spoken of as more remote descendants. In this list Ehi ( 'ēḥı̄ ) is perhaps Ahiram shortened. See Aharah; Aher; Ehi .
