متى ٦:١٦

Moreover, when ye fast--referring, probably, to private and voluntary fasting, which was to be regulated by each individual for himself; though in spirit it would apply to any fast. be not, as the hypocrites, of a sad countenance: for they disfigure their faces--literally, "make unseen"; very well rendered "disfigure." They went about with a slovenly appearance, and ashes sprinkled on their head. that they may appear unto men to fast--It was not the deed, but reputation for the deed which they sought; and with this view those hypocrites multiplied their fasts. And are the exhausting fasts of the Church of Rome, and of Romanizing Protestants, free from this taint? Verily I say unto you, They have their reward.

We are here cautioned against hypocrisy in fasting, as before in almsgiving, and in prayer. I. It is here supposed that religious fasting is a duty required of the disciples of Christ, when God, in his providence, calls to it, and when the case of their own souls upon any account requires it; when the bridegroom is taken away, then shall they fast, Mat 9:15. Fasting is here put last, because it is not so much a duty for its own sake, as a means to dispose us for other duties. Prayer comes in between almsgiving and fasting, as being the life and soul of both. Christ here speaks especially of private fasts, such as particular persons prescribe to themselves, as free-will offerings, commonly used among the pious Jews; some fasted one day, some two, every week; others seldomer, as they saw cause. On those days they did not eat till sun-set, and then very sparingly. It was not the Pharisee's fasting twice in the week, but his boasting of it, that Christ condemned, Luk 18:12. It is a laudable practice, and we have reason to lament it, that is so generally neglected among Christians. Anna was much in fasting, Luk 2:37. Cornelius fasted and prayed, Act 10:30. The primitive Christians were much in it, see Act 13:3; Act 14:23. Private fasting is supposed, Co1 7:5. It is an act of self-denial, and mortification of the flesh, a holy revenge upon ourselves, and humiliation under the hand of God. The most grown Christians must hereby own, they are so far from having any thing to be proud of, that they are unworthy of their daily bread. It is a means to curb the flesh and the desires of it, and to make us more lively in religious exercises, as fulness of bread is apt to make us drowsy. Paul was in fastings often, and so he kept under this body, and brought it into subjection. II. We a…

6:16 Prayer and fasting are frequently connected (Lev 23:27-32; Neh 9:1-2; Zech 7:3-5; 8:19; Luke 18:12). The practice had been abused before Jesus’ time (Isa 58:3-12).
