2 Peter 1:13-14

Peter’s earthly dwelling (lit. tent) was his physical body (cf. 2 Corinthians 5:1; 2 Corinthians 5:4). The Greek word apothesis means "a divesting," and it refers elsewhere to removing clothes (cf. Acts 7:58). We do not know exactly how Peter knew someone would separate his mortal body from his spirit soon. Peter’s words allow the possibility of separation by death or translation. Both events were imminent: overhanging. He was probably at least in his 50s, if not older, when he wrote 2 Peter, and he may have known that he would die as a martyr soon. The Lord Jesus had told Peter that he would end his earthly life as a captive of some kind (John 21:18-19).
