Ye shall weep ... - At my crucifixion, sufferings, and death. Compare Luke 23:27.
The world - Wicked men. The term world is frequently used in this sense. See John 16:8. It refers particularly, here, to the Jews who sought his death, and who would rejoice that their object was obtained.
Shall be turned into joy - You will not only rejoice at my resurrection, but even my death, now the object of so much grief to you, will be to you a source of unspeakable joy. It will procure for you peace and pardon in this life, and eternal joy in the world to come. Thus their greatest apparent calamity would be to them, finally, the source of their highest comfort; and though then they could not see how it could be, yet if they had known the whole case they would have seen that they might rejoice. As it was, they were to be consoled by the assurance of the Saviour that it would be for their good. And thus, in our afflictions, if we could see the whole case, we should rejoice. As it is, when they appear dark and mysterious, we may trust in the promise of God that they will be for our welfare. We may also remark here that the apparent triumphs of the wicked, though they may produce grief at present in the minds of Christians, will be yet overruled for good. Their joy shall be turned into mourning, and the mourning of Christians into joy; and wicked men may be doing the very thing - as they were in the crucifixion of the Lord Jesus - that shall yet be made the means of promoting the glory of God and the good of his people, Psalms 76:10.
