Parallel
Isaiah 41:7
Brenton's English Septuagint · Berean Standard Bible
The artificer has become strong, and the coppersmith that smites with the hammer, [and] forges also: sometimes he will say, It is a piece well joined: they have fastened them with nails; they will fix them, and they shall not be moved.
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.
