This noun refers to the act of putting off or laying aside something—most concretely clothing, but metaphorically extended to other kinds of removal or resignation. Peter uses it twice in contexts that blend physical and spiritual imagery. In 1 Peter 3:21, baptism is 'not a removal of dirt from the body' but an appeal to God. In 2 Peter 1:14, the apostle speaks of the imminent 'putting off of my tent' (his body/death) as Christ revealed to him. Classical usage included storing things away, exposure of children, even resignation from office—but the New Testament focuses on the metaphor of removing or laying aside what was previously worn or inhabited.
