Charles Ellicott Commentary 1 Chronicles 15:10

"of the sons of Uzziel, Amminadab the chief, and his brethren a hundred and twelve." — 1 Chronicles 15:10 (ASV)

Of the sons of Uzziel. — Uzziel was the fourth son of Kohath (1 Chronicles 6:2). Exodus 6:22 names three sons of Uzziel: Mishael, Elzaphan, and Zithri. The family of Elzaphan has already been represented (1 Chronicles 15:8). The term “sons of Uzziel,” therefore, in this verse represents the two other Uzzielite houses, which may have amalgamated into one. As Elzaphan is mentioned first, the elder line of Mishael may have become extinct. At any rate, 1 Chronicles 23:20 and 1 Chronicles 24:24 imply the existence of only two Uzzielite stocks.
