1 Chronicles 4:21-22

Shelah was Judah’s son. Shelah’s sons were Er, Laadah, Jokim, the men from Cozeba, Joash, and Saraph. Er was the father of Lecah. Laadah was the father of Mareshah and the family groups of linen workers at Beth Ashbea. Joash and Saraph ruled in Moab and Jashubi Lehem. The writings about this family are very old.
