The ironsmith makes an idol (Isa 44:12-44:12)

“The ironsmith fashions it.

He works it over the coals.

He shapes it with hammers.

He forges it with his strong arm.

He becomes hungry.

His strength fails.

He drinks no water.

He is faint.”

Second Isaiah calls out the ironsmith for special attention. He has to work hard to produce this idol. He uses coal, hammers, and a strong arm. However, this blacksmith gets hungry and thirsty, so that his strength fails and he faints.
