Verse 20. - This is the first occasion on which our Lord alludes to his removal from them. The bridegroom shall be taken away from them. The Greek word (ἀπαρθῇ) conveys the idea of a painful severance. And then will they fast in that day (ἐν ἐκείνῇ τῇ ἡμέρα). This is the true reading. After our Lord's death, his disciples frequently fasted as of necessity, and went through much privation and trial. And so it must be for the most part with all who will live godly in Christ Jesus, until he returns to take to himself his kingdom, when there will be a glad and everlasting festival.

2:18-22 Strict professors are apt to blame all that do not fully come up to their own views. Christ did not escape slanders; we should be willing to bear them, as well as careful not to deserve them; but should attend to every part of our duty in its proper order and season.But the days will come,.... As they were in some sense now come to the disciples of John, their master being taken up by Herod, and confined in prison, and so it was a mourning time with them:

when the bridegroom shall be taken away from them, and then shall they fast in those days: referring to the time of the sufferings and death of Christ, which would be, and was a sorrowful season to his disciples.
