Charles Ellicott Commentary 2 Samuel 23:36

"Igal the son of Nathan of Zobah, Bani the Gadite," — 2 Samuel 23:36 (ASV)

Igal. —Chronicles has Joel. The two names differ in Hebrew only in one letter, and that a very similar one; but he is described here as the son of Nathan of Zobah, in Chronicles as the brother of Nathan. Brother is in Hebrew ahi, and some manuscripts in Chronicles read the son of Ahinathan. If this is accepted, the only difference would be in the form of a name, Nathan or Ahinathan.

Bani the Gadite. —In Chronicles Mibhar the son of Haggeri. Entirely unlike as these readings appear, they are not so very different in the original. Mibhar is for Zobah of the previous clause, a word at present missing in Chronicles; the son of (Ben) is for Bani; and the Gadite (with the article) differs from Haggeri only by the change of the often confused letters d and r. The text here is the true one.
