Isaiah 41:7

So the carpenter encourages the goldsmith. He who smooths with the hammer encourages him who strikes the anvil, saying of the soldering, “It is good;” and he fastens it with nails, that it might not totter.

So the carpenter encouraged the goldsmith, and he that smootheth with the hammer him that smote the anvil, saying, It is ready for the sodering: and he fastened it with nails, that it should not be moved.
