'Dead Rise' in the Bible

And indeed we are found false witnesses of God; because we have testified concerning God that he raised up Christ: whom he raised not, if in truth the dead rise not.

For if the dead rise not, then is not Christ raised:

Else what will they do, who are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?

If after the manner of men I have fought with beasts at Ephesus, what advantage is it to me, if the dead rise not? let us eat and drink; for to-morrow we die.
