1 Corinthians 15:29 in the King James Version
Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?
Context
28 When all things have been subjected to him, then the Son will also himself be subjected to him who subjected all things to him, that God may be all in all.
29 Or else what will they do who are baptized for the dead? If the dead aren’t raised at all, why then are they baptized for the dead?
30 Why do we also stand in jeopardy every hour?
