'Fallen' in the Bible

That [careless and unworthy participation] is the reason why many among you are weak and sick, and a number sleep [in death].

After that He appeared to more than five hundred brothers and sisters at one time, the majority of whom are still alive, but some have fallen asleep [in death].

But now [as things really are] Christ has in fact been raised from the dead, [and He became] the first fruits [that is, the first to be resurrected with an incorruptible, immortal body, foreshadowing the resurrection] of those who have fallen asleep [in death].
