It might appear so at first sight, but upon closer scrutiny, we will see that there is no contradiction.
Isaiah 26:13-14 states: “O LORD our God, masters besides You Have had dominion over us; But by You only we make mention of Your name. They are dead, they will not live; They are deceased, they will not rise. Therefore You have punished and destroyed them, And made all their memory to perish.”
On the other hand, we read in Isaiah 26:19:
“Your dead shall live; Together with my dead body they shall arise. Awake and sing, you who dwell in dust; For your dew is like the dew of herbs, And the earth shall cast out the dead.”
"You are the light of the world. A city that is set on a hill cannot be hidden."
-Matthew 5:14
