1 Chronicles 4:14

And Meonothai
Another son of Othniel:

begat Ophrah; and Seraiah, the brother of Othniel, begat Joab;
not David's general, but another of the same name, who lived long before him, see ( 1 Chronicles 2:54 )

the father of the valley of Charashim:
of the inhabitants of the valley, or the prince of them, called the valley of craftsmen, ( Nehemiah 11:35 ) the reason of which is here given:

for they were craftsmen;
that dwelt in it, carpenters and smiths, both which the word signifies, men that wrought in stone, wood, and iron.
