The sons of Shelah son of Judah: Er the father of Lecah, Laadah the father of Mareshah and the family of linen workers at Beth Ashbea, Jokim, the men of Cozeba, and Joash and Saraph, who ruled in Moab and Jashubi Lehem. (These records are from very old traditions.) They were the potters who lived at Netaim and Gederah, resident potters who worked for the king.
