'Potters' in the Bible

These were the potters, and the inhabitants of Netaim and Gederah: there they dwelt with the king for his work.

And whereas thou sawest the feet and toes, part of potters clay, and part of iron, it shall be a divided kingdom; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay.
