The dead shall rise (Isa 26:19-26:19)

“Your dead shall live!

Your corpses shall rise!

O dwellers in the dust!

Awake!

Sing for joy!

Your dew is radiant dew!

The earth will give birth

To those long dead.”

However, Isaiah has new hope. The dead will rise. This was a general theme after the Exile, not prior to it. Clearly this text of Isaiah is talking about a general resurrection. The dead would live. The corpses would rise. In fact, there is a call to dust dwellers to wake up and sing for joy. This new birth is from the dead, even those long dead, not from pregnant women. Is this just a call for the Israelites to rise up or is this a general belief in the last day resurrection?
