Did the Old Testament Jews believe in resurrection?


But your dead will live, Lord;
    their bodies will rise—
let those who dwell in the dust
    wake up and shout for joy—
your dew is like the dew of the morning;
    the earth will give birth to her dead. Isaiah 26:19
            Yes. Even before Jesus, the Jews believed they would rise again.  Psalms describes this and David expresses it when his stillborn son dies (2 Samuel 12:23).  Jesus came to earth to confirm and visually display that resurrection the Jews already believed.
