14 They are now dead, they live no more; their spirits do not rise. You punished them and brought them to ruin; you wiped out all memory of them.

Read Isaiah 26:14 Using Other Translations

They are dead, they shall not live; they are deceased, they shall not rise: therefore hast thou visited and destroyed them, and made all their memory to perish.
They are dead, they will not live; they are shades, they will not arise; to that end you have visited them with destruction and wiped out all remembrance of them.
Those we served before are dead and gone. Their departed spirits will never return! You attacked them and destroyed them, and they are long forgotten.
