(16) Men and brethren.--Better, brethren only, the word being used as in the LXX. of Genesis 13:8. The tone of St. Peter's speech is that of one who felt that his offence had been fully forgiven, and that he was now restored by the charge given him, as in John 21:15-17, to his former position as guide and leader of the other disciples. To do that work faithfully was a worthier fruit of repentance than any public confession of his guilt would have been. This, of course, does not exclude--what is in itself probable--that he had previously confessed his fault, either to his special friend St. John, or to the whole company of Apostles and other disciples.

Which the Holy Ghost by the mouth of David spake . . .--We have here, obviously, the firstfruits of the new method of interpretation in which the Apostles had been instructed (Luke 24:27; Luke 24:45). They had already been taught that the Holy Spirit which their Lord had promised to them had before spoken by the prophets. The recurrence of the same mode of speech in the "holy men of God who spake as they were moved (literally, borne along) by the Holy Ghost," in 2Peter 1:21, is, as far as it goes, evidence in favour of the genuineness of that Epistle.

Which was guide to them that took Jesus.--The actual word "guide" is not found in the Gospel narrative, but it appears as a fact in all four, notably in that of St. John (John 18:2-3).

Verse 16. - Brethren, it teas needful that the Scripture should be fulfilled for men and brethren, this Scripture must needs have been fulfilled, A.V.; spake before by the mouth of David for by the mouth of David spake before, A.V. It was needful, etc. So our Lord declared, "The Scriptures cannot be broken" (John 10:35); and "All things must be fulfilled which were written" ere. (Luke 24:25-27, 44-46). It is most important to our Christian integrity that we should view the Scriptures in the same light as our Lord and his apostles did, as containing real prophecies, spoken by the Holy Ghost. (Compare the manner in which the sixty-ninth psalm is here quoted with that of Hebrews 3:7.) So the Creed, "I believe in the Holy Ghost .... who spake by the prophets" (comp. Acts 4:25; Acts 28:25). Who was guide, etc. If St. Peter had only been addressing his brother apostles, who were well acquainted with the treachery of Judas, it would scarcely have been natural to introduce these words; they would have seemed rather to be explanatory words added by the historian. But the circumstances might be very imperfectly known to many of the hundred and twenty brethren assembled on this occasion; and if so, the reference to Judas's treachery would not be out of place in St. Peter's mouth.

1:15-26 The great thing the apostles were to attest to the world, was, Christ's resurrection; for that was the great proof of his being the Messiah, and the foundation of our hope in him. The apostles were ordained, not to wordly dignity and dominion, but to preach Christ, and the power of his resurrection. An appeal was made to God; Thou, Lord, who knowest the hearts of all men, which we do not; and better than they know their own. It is fit that God should choose his own servants; and so far as he, by the disposals of his providence, or the gifts of his Spirit, shows whom he was chosen, or what he has chosen for us, we ought to fall in with his will. Let us own his hand in the determining everything which befalls us, especially in those by which any trust may be committed to us.Men and brethren,.... Which is said not so much by Peter to express his modesty, and humility, and his brotherly love; or on account of the spiritual relation that subsisted between him and the persons he speaks to, as it was a common form used in addresses; see Acts 7:2 it should seem, that the women, were not reckoned into the number of the hundred and twenty here addressed; and the Syriac version calls that number, "the number of men", unless they are supposed to be included in them:

this Scripture must needs have been fulfilled; or "must needs be fulfilled": referring either to Psalm 41:9 or rather to the passages after cited out of Psalm 69:25. There was a necessity of the fulfilling of it, consistent with the prescience of God, his counsel, and decree, and the veracity of the Scripture; which necessity does not at all excuse the sin of Judas, who acted freely from the wickedness of his own heart, and not from any force that this laid upon him: and the apostle might observe this also, to make the minds of the disciples easy, under this awful providence, since it was no other than what was predicted: and

which the Holy Ghost, by the mouth of David, spake before; even many hundreds of years before the event; and which shows the omniscience, and so the deity of the Holy Ghost, and the divine authority of David's Psalms; as well as the honour that was put upon him to be the instrument by which the Holy Ghost speaks, and to be his amanuensis: the particular referred to, is, "concerning" Judas; who is sometimes called Iscariot, to distinguish him from another apostle of the same name; and what is hereafter said sufficiently does that; or

concerning that Judas, as the Syriac version renders it:

which was a guide to them that took Jesus; to the band of soldiers and officers, who came with swords and staves, as to take a thief, or a robber; before these Judas went and showed them, not only the place where he was, but gave them a sign by which they should know him, and also advice to take him and hold him fast, and lead him away safely; so that he was not only a guide as to the way, but was a director, and conductor, and manager of the whole affair. And it may be observed, that though Peter did not conceal, but declares the sin of Judas; yet not in a rough manner, aggravating it, but with much softness and tenderness; though with no design to lessen it, as appears by what follows, and which may be instructive to us in speaking of other men's sins.
