John Gill Commentary 1 Chronicles 2:52

"And Shobal the father of Kiriath-jearim had sons: Haroeh, half of the Menuhoth." — 1 Chronicles 2:52 (ASV)

And Shobal, the father of Kirjathjearim had sons
Which shows that Kirjathjearim is not the name of a man, or of any of Shobal's sons, who are next mentioned, but of a place of which he was prince: the first is

Haroeh ,
who is called Reaiah, (1 Chronicles 4:2) a word of the same signification:

and half of the Manahethites ;
which Kimchi takes to be the proper name of a man called Chatzihamanaheth, another son of Shobal's; but Jarchi interprets it of the name of a place or province called Manahath, (1 Chronicles 8:6) over half of which Haroeh was governor.
