(22–23) The sons of Kohath. As the text stands we have here a threefold list, each portion of which is isolated from the rest, and begins afresh with the word onê (the sons of).
(22) Amminadab his son. — Amminadab is not mentioned as a son of Kohath in the Pentateuch or elsewhere. Korah, here called son of Amminadab, is called son of Izhar, son of Kohath, Exodus 6:21. (See 1 Chronicles 6:18, supra, and 1 Chronicles 6:38, infra.) Some assume that Amminadab is a “by-name” of Izhar (so Margin). It is more likely that the name Izhar has dropped out of the text of 1 Chronicles 6:22.
(22, 23) Assir his son, Elkanah his son, and Ebiasaph his son. — Comp. Exodus 6:24 : “And the sons of Korah, Assir, and Elkanah, and Abiasaph, these are the sons of Korah.” The connection, then, is as follows: —
The conjunction and, in 1 Chronicles 6:23, seems to hint that the connection is no longer one of direct descent, but that the three, Assir, Elkanah, and Ebiasaph, are to be regarded as brothers.
(23) And Assir his son. — Comp. 1 Chronicles 6:37 below, in the line of Heman, which in great part coincides with the present series. There we read, “Assir, son of Ebiasaph, son of Korah.” The present Assir is therefore son of Ebiasaph, and nephew of the former Assir (1 Chronicles 6:22). The form of a direct descent is now resumed and continued with Tahath, son of Assir (1 Chronicles 6:24).
