Matthew 9:14 - Ellicott's Commentary On The Whole Bible

The disciples of John. — The passage is interesting as showing (1) that the followers of the Baptist continued during our Lord’s ministry to form a separate body (as in Matthew 11:2; Matthew 14:12); and (2) that they obeyed rules which he had given them, more or less after the pattern of those of the Pharisees. They had their own days of fasting (the context makes it probable that the feast in Matthew’s house was held on one of them), their own forms of prayer (Luke 11:1). They, it would seem, acting with the Pharisees, and perhaps influenced by them, were perplexed at conduct so unlike that of the master they revered, and came therefore with their question. But they were, at least, not hypocrites, and they are answered therefore without the sternness which had marked the reply to their companions.
