Matthew 8:16 - Ellicott's Commentary On The Whole Bible

When the even was come. — Or, as St. Luke has it, “While the sun was setting.” There were two reasons why the time should be thus specified. (1) It was natural that the sick should be brought in the cool of the evening, rather than in the scorching heat of the afternoon; and (2) it was the Sabbath, and the feeling which made the Pharisees question the lawfulness of a man’s carrying the bed on which he had been lying (John 5:10), would probably have deterred the friends of the sick from bringing them as long as it lasted. But with sunset the Sabbath came to a close, and then they would feel themselves free to act. The prominence given to “those that were possessed with devils,” both by St. Matthew and St. Mark, shows that it was the work of the Sabbath morning that had most impressed itself on their minds.
