(29) After my departing shall grievous wolves enter in among you.--The figurative language followed naturally on the idea of the flock and of the shepherds who keep watch over it. It lies in the nature of the case that the wolf stands primarily for the open enemies of the flock, the persecutors of all ages. (Comp. John 10:12.) The wolves, however, might come in sheep's clothing (Matthew 7:15), and so the false prophets, the usurpers of authority, and leaders of parties within the Church, are also included in the term. Here this latter class is distinctly pointed out in the following verse. We find traces of the fulfilment of the prediction in the "turning away" of 2Timothy 1:15; the "fiery trial" of 1Peter 1:7; 1Peter 4:12; the suffering "as a Christian" of 1Peter 4:16.

Verse 29. - I know for, for I know this, A.V. and T.R.; grievous wolves shall for shall grievous wolves, A.V. After my departure (ἄφιξιν, not ἀνάλυσιν, as 2 Timothy 4:6). The word, which is only found here in the New Testament, usually means "arrival" in classical Greek, but it also means, as here, "departure." It is not to be taken in the sense of "departure from this life," but refers to that separation, which he thought was forever, which was about to take place. Grievous wolves; still keeping up the metaphor of the flock. The wolves denote the false teachers, principally Judaizers. See 2 Timothy 3:1-12, and 13, "But evil men and seducers shall wax worse and worse, deceiving, and being deceived." These came from Judaea.

20:28-38 If the Holy Ghost has made ministers overseers of the flock, that is, shepherds, they must be true to their trust. Let them consider their Master's concern for the flock committed to their charge. It is the church He has purchased with his own blood. The blood was his as Man; yet so close is the union between the Divine and human nature, that it is there called the blood of God, for it was the blood of Him who is God. This put such dignity and worth into it, as to ransom believers from all evil, and purchase all good. Paul spake about their souls with affection and concern. They were full of care what would become of them. Paul directs them to look up to God with faith, and commends them to the word of God's grace, not only as the foundation of their hope and the fountain of their joy, but as the rule of their walking. The most advanced Christians are capable of growing, and will find the word of grace help their growth. As those cannot be welcome guests to the holy God who are unsanctified; so heaven would be no heaven to them; but to all who are born again, and on whom the image of God is renewed, it is sure, as almighty power and eternal truth make it so. He recommends himself to them as an example of not caring as to things of the present world; this they would find help forward their comfortable passage through it. It might seem a hard saying, therefore Paul adds to it a saying of their Master's, which he would have them always remember; It is more blessed to give than to receive: it seems they were words often used to his disciples. The opinion of the children of this world, is contrary to this; they are afraid of giving, unless in hope of getting. Clear gain, is with them the most blessed thing that can be; but Christ tell us what is more blessed, more excellent. It makes us more like to God, who gives to all, and receives from none; and to the Lord Jesus, who went about doing good. This mind was in Christ Jesus, may it be in us also. It is good for friends, when they part, to part with prayer. Those who exhort and pray for one another, may have many weeping seasons and painful separations, but they will meet before the throne of God, to part no more. It was a comfort to all, that the presence of Christ both went with him and stayed with them.For I know this,.... By divine revelation:

that after my departing; either out of this world, or after his leaving them now, and proceeding on, his journey:

shall grievous wolves enter in among you; false teachers, comparable to wolves, for their craft and cunning, and for their greedy, covetous, and voracious dispositions; and who would be very grievous, troublesome, and even intolerable to them; these, he knew, would enter privily, at an unawares, into their churches, and set up themselves for preachers, without being called or sent:

not sparing the flock; fleecing it instead of feeding it, making merchandise of it, and like the Pharisees, under religious pretences, devour widows' houses, and drain the purses of men; and having as little compassion upon their souls, poisoning them with their errors and heresies, subverting their faith, and bringing them into swift ruin and destruction, as much as would in them lie.
