The craftsman encourages the goldsmith, and he who wields the hammer cheers him who strikes the anvil, saying of the welding, “It is good.” He nails it down so it will not be toppled.
Jewish Publication Society of America Version (JPS1917) - Isaiah 41:7 >So the carpenter encouraged the goldsmith, and he that smootheth with the hammer him that smiteth the anvil, saying of the soldering: 'It is good'; and he fastened it with nails, that it should not be moved.
