Craftsmen encourage goldsmiths. Metalsmiths encourage blacksmiths who work at their anvils. They say that their soldering is good. And they fasten things with nails so they won’t move.
Blacksmiths shape iron into tools. They work them over the coals and shape them with hammers, working them with their strong arms. They get hungry, and their strength fails. If they don’t drink water, they will faint.
