18. The disciples of John. [The Question About Fasting, Mark 2:18-22=Matt. 9:14-17=Luke 5:33-39. Major comment: Mark. See Middle Galilean Ministry; on parables 203-207.]
Used to fast. Probably better, “were fasting.” Doubtless John’s disciples shared at least to some extent in his abstemious way of life (see Matt. 3:4), as is evidenced here by their fasting. It seems clear that they were, indeed, fasting at the very time they brought their question to Jesus.
An ancient Jewish treatise on fasting from the 1st century , Megillath Ta‘anith, mentions Jews who at that time regularly fasted on the second and fifth days of the week, that is, Monday and Thursday (see Luke 18:12). Although Jewish tradition attributes this custom to the story that Moses began his 40-day fast on Mt. Sinai (see Ex. 34:28) on a Thursday and terminated it on a Monday, it seems probable that the observance of these two days as fasts actually arose from the desire to keep them as far as possible from the Sabbath, and at the same time not to have them too close together. See Strack and Billerbeck, Kommentar zum Neuen Testament, 2, 241-243.
Strack and Billerbeck, leading authorities on ancient Judaism, indicate that the exact motives behind these biweekly fasts are not entirely clear, but it seems probable that they arose through a desire on the part of particularly earnest people to seek to atone for the worldliness of the nation, which they felt was fast bringing on its destruction. In general among the ancient Jews fasting was undertaken by individuals in order to make good a misdeed or to ensure the favorable answer to a prayer or fulfillment of a wish. Indeed, many seem to have fasted because they believed such an act earned special merit for them before God.
These uses of fasting rested, of course, upon a misconception of the character of God and of the nature of righteousness. Too often fasting degenerated into a means of righteousness by works through which men hoped to appease an austere God and earn His favor, regardless of the state of their hearts. Centuries before the time of Jesus the prophets had denounced such ideas, declaring that God had come to abhor Israel’s fasts and other religious observances (Isa. 58:3-5; Zech. 7:5, 6).
There are times when the Christian needs keenness of thought and discriminating judgment; he may have important decisions to make, or may need to discern more clearly the will of God. Under such circumstances fasting can prove a great blessing. Such fasting may not necessarily mean complete abstinence from food, but a diet limited to the simple essentials for maintaining health and vigor. The Christian may, like Daniel, refrain from the use of “pleasant bread” (Dan 10:3). God is not honored and one’s Christian experience is not promoted by any practice that weakens the body or impairs the health. See Matt. 6:16.
They come and say. Those here designated are not clearly identified, nor is the Gospel of Luke clearer in this respect (see Luke 5:33). However, Matthew states definitely that it was the disciples of John the Baptist who plied Jesus with the query in regard to fasting (Matt. 9:14).
According to the tentative chronology adopted in this commentary, John had been imprisoned in the early spring of this year, 29, and probably was executed shortly before the Passover of 30 (see on Matt. 4:12; Mark 6:14-29; Luke 3:19, 20). His disciples raised their question on fasting probably not more than a few months before he died.
Thy disciples fast not. Thus the scribes apparently hoped to alienate the rapidly growing body of disciples from their Master.
