'Decay' in the Bible

So it is with the resurrection of the dead. The [human] body that is sown is perishable and mortal, it is raised imperishable and immortal.

in a moment, in the twinkling of an eye, at [the sound of] the last trumpet call. For a trumpet will sound, and the dead [who believed in Christ] will be raised imperishable, and we will be [completely] changed [wondrously transformed].
