Meonothai was the father of Ophrah. Seraiah was the father of Joab. Joab was the father of Ge Harashim. Ge Harashim was called by that name because all its people were skilled workers.
Other sons of Shelah were Jokim, Joash, Saraph and the men of Kozeba. Moab and Jashubi Lehem were ruled by sons of Shelah. The records of all these matters are very old.
