Hastings' Dictionary of the Bible [1]

Harodite . A designation applied in   2 Samuel 23:25 to two of David’s heroes, Shammah and Elika. The second is wanting in LXX [Note: Septuagint.] and in the parallel list in   1 Chronicles 11:27 . In the latter passage, by a common scribal error ‘the Harodite’ has been transformed into ‘the Harorite .’ ‘The Harodite’ was probably a native of ‘Ain-harod ( Jalud ),   Judges 7:1 . See preceding article.

Morrish Bible Dictionary [2]

Designation of Shammah and Elika, two of David's mighty men, probably from some place called Harod.  2 Samuel 23:25 . Apparently the former is called Shammoth the HARORITE in  1 Chronicles 11:27 .

hā´rod - ı̄t ( חרדי , ḥărōdhı̄ ): Two of David's heroes, Shamma and Elika, are so called (  2 Samuel 23:25 ). Septuagint omits the second name. In  1 Chronicles 11:27 , the first is called "Shammoth the Harorite," while the second is omitted. "Harorite" is a clerical error for "Harodite," the Hebrew letter daleth ד ("d") being taken for the Hebrew letter resh ר ("r"). Possibly Harodite may be connected with the well of Harod (which see).

(Heb. Charodi', חֲרדי , Sept. Ἀροδί ), an epithet of Shammah and Elika, two of David's heroes ( 2 Samuel 23:25), probably from their being natives of HAROD, a place near the fountain of the same name ( Judges 7:1). (See Harorite).
