A blacksmith works with his tool and forges metal over the coals. He forms it with hammers; he makes it with his strong arm. He gets hungry and loses his energy; he drinks no water and gets tired.

The craftsman encourages the metalsmith, the one who wields the hammer encourages the one who pounds on the anvil. He approves the quality of the welding, and nails it down so it won't fall over."

And He will judge between the nations,
And will render decisions for many peoples;
And they will hammer their swords into plowshares and their spears into pruning hooks.
Nation will not lift up sword against nation,
And never again will they learn war.

For the fitches are not crushed with a sharp instrument, and a cart-wheel is not rolled over the cummin; but the grain of the fitches is hammered out with a stick, and of the cummin with a rod.
