1 Chronicles 4:21-23

21These were the sons of Judah's son, Shelah: Er, Laadah, Jokim, Joash, Saraph and Jashubi-Lehem. Er became the father of Lecah. Laadah became the father of Mareshah. Joash and Saraph both married women from Moab and they returned to live in Lehem. Other clans that were descendants of Shelah worked with linen at Beth-Ashbea, and some lived in Cozeba. (These lists are from old history books.)

23Those people made pots. They lived in Netaim and Gederah. They lived there and they worked for the king.
