New Defender's Study Bible Notes
1:14 my tabernacle. Peter’s “tabernacle” was actually a frail “tent” (Greek skenoma), erected just for a night. He had used the same word in Matthew 17:4, speaking of making three tents for the heavenly visitors on the Mount of Transfiguration. In II Peter 1:15, he speaks of his imminent decease, just as those heavenly visitors had spoken of Christ’s imminent decease at Jerusalem (Luke 9:31). Both of these words are rarely used in the New Testament, and their appropriation of them here in similar juxtaposition is an incidental confirmation of the authenticity of Peter’s claimed authorship of this epistle. Paul also had written about putting off the tent of these present bodies (II Corinthians 5:1).
1:14 shewed me. Peter here refers to the Lord’s prophecy in John 21:17-19, indicating a coming martyrdom for Peter, possibly by crucifixion. The fact that it would come shortly is probably in recognition of his advancing age, although it may possibly suggest that a rapid (that is, violent, by execution) death was coming.
