2 Peter 1:14

“Knowing that shortly I must put off this my tabernacle, etc.] Which is another reason why the apostle was so pressing in this case, and so much urged the exhortation, and was so diligent in reminding the saints of it, and stirring them to observe it, because he knew he had but a little time to live, and which therefore he was willing to improve for their good. He sets forth his death in a very easy and familiar way, it being not at all terrible and distressing to him; it was but like the putting off of a garment, or unpinning of a tabernacle, or a removing from a tent to a palace. Saints are pilgrims here, they dwell in tents or tabernacles, at death they remove to their own country, and…”

“shortly I must put off--Greek, "the putting off (as a garment) of my tabernacle is speedy": implying a soon approaching, and also a sudden death (as a violent death is). Christ's words, Joh 21:18-19, "When thou art old," &c., were the ground of his "knowing," now that he was old, that his foretold martyrdom was near. Compare as to Paul, Ti2 4:6. Though a violent death, he calls it a "departure" (Greek for "decease," Pe2 1:15), compare Act 7:60.”

“Knowing that shortly I must put off this my tabernacle - That I must die. This he knew, probably, because he was growing old, and was reaching the outer period of human life. It does not appear that he had any express revelation on the point. Even as our Lord Jesus Christ hath shewed me - See the notes at John 21:18-19. This does not mean that he had any new revelation on the subject, showing him that he was soon to die, as many of the ancients supposed; but the idea is, that the time drew near when he was to die “in the manner” in which the Saviour had told him that he would. He had said John 21:18 that this would occur when he should be “old,” and as he was now becoming old, he felt that…”

“Even as the Lord Jesus showed me - In the manner which had foretold, Joh 21:18, &c. It is not improbable, he had also showed him that the time was now drawing nigh. 2 Peter 1:15”

“1:14 This prophecy might have come in a vision, but it is more likely that Peter was recalling Jesus’ prophecy about his death (John 21:18-19).”

“shortly: Deu 4:21, Deu 4:22, Deu 31:14; Jos 23:14; Kg1 2:2, Kg1 2:3; Act 20:25; Ti2 4:6 even: Joh 21:18, Joh 21:19 2 Peter 1:15”
