'Chisel' in the Bible

What right do you have to be here? What relatives do you have buried here? Why do you chisel out a tomb for yourself here? He chisels out his burial site in an elevated place, he carves out his tomb on a cliff.

The iron-smith hath a chisel, and he worketh in the coals, and he fashioneth it with hammers, and worketh it with his strong arm; but he is hungry, and his strength faileth; he hath not drunk water, and he is faint.
