John Gill Commentary 1 Chronicles 5:24

"And these were the heads of their fathers` houses: even Epher, and Ishi, and Eliel, and Azriel, and Jeremiah, and Hodaviah, and Jahdiel, mighty men of valor, famous men, heads of their fathers` houses." — 1 Chronicles 5:24 (ASV)

And these were the heads of the house of their fathers
Some of the principal men of this half tribe:

even Epher, and Ishi, and Eliel, and Azriel, and Jeremiah, and
Hodaviah, and Jahdiel ;
but of none of these we read elsewhere, excepting Hepher and Azriel, (Numbers 26:31Numbers 26:32)

mighty men of valour, famous men, and heads of the house of their
fathers ;
men that obtained a name for their strength, courage, and valour, and military exploits, and were the chiefs of the families in this half tribe, and by whom they were denominated; so from Hepher were the family of the Hepherites, and from Azriel the family of the Azrielites, as in the place before quoted.
