The translators of the NASB certainly did not differentiate between corpse and dead body:

Quote
Isaiah 26:19- " Your dead will live; Their [color:"red"]corpses[/color] will rise. You who lie in the dust, awake and shout for joy, for your dew is as the dew of the dawn, and the earth will give birth to the departed spirits."

Quote
Isaiah 66:24- "Then they will go forth and look on the [color:"red"]corpses[/color] of the men who have transgressed against Me. For their worm will not die and their fire will not be quenched; And they will be an abhorrence to all mankind."

True godliness is a sincere feeling which loves God as Father as much as it fears and reverences Him as Lord, embraces His righteousness, and dreads offending Him worse than death~ Calvin
