Isaiah 40:20

40:20 To make a contribution one selects wood that will not rot;

he then seeks a skilled craftsman

to make an idol that will not fall over.

Isaiah 41:7

41:7 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.”
