1 Chronicles 4:21 ERV

[21] 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 tribes of linen workers at Beth Ashbea. Joash and Saraph married Moabite women. Then they went back to Bethlehem. The writings about this family are very old.
