John Gill's Exposition of the Whole Bible
1 Chronicles 2:47
And the sons of Jahdai,.... Who is not mentioned by this name before; perhaps the same with Moza, who might have two names, though, according to Hillerus t, he was the son of Moza; some take it to be the name of another of Caleb's concubines, by whom he had the six following sons:
Regem, and Jotham, and Geshan, and Pelet, and Ephah, and Shaaph; one of these, Pelet perhaps, gave name to Bethpalet in the tribe of Judah, Joshua 15:27.
