What does 1 Chronicles 7:2 mean?

John Gill's Exposition of the Bible
1 Chronicles 7:2

And the sons of Tola
The eldest son of Issachar, whose posterity are only reckoned by name:

Uzzi, and Rephaiah, and Jeriel, and Jahmai, and Jibsam, and Shemuel,
heads of their father's house, to wit, of Tola;
the principal man of his family:

[they] were valiant men of might in their generations,
famous for their courage and military exploits, though they sprang from Tola, whose name signifies "a worm"; and which name Bochart F11 conjectures was given him by his parents, because he was so weakly that they had no hopes of raising him; and yet from him sprung such mighty men, and from them such a numerous race, as follows:

whose number was, in the days of David, two and twenty thousand and six
hundred;
besides those of the posterity of Uzzi, after mentioned. This was at the time Joab took the number of Israel, by the order of David, ( 1 Chronicles 21:5 ) .
