This fast was not any necessitated abstinence, but a religious fast, as the word here used does most commonly signify; and the article being put to it, it may well denote some eminent and known fast. We read, that amongst the Jews several fasts were observed; as the fast of the fourth month, of the fifth month, of the seventh, and of the tenth month, Malachi 8:19. But that of the seventh month did far exceed them all, it being the day in which the priest was to make an atonement for the people; and they were strictly commanded to afflict their souls in it, Leviticus 16:29, Leviticus 23:27. (Thus when we look up to him whom by our sins we have pierced, we must mourn, Malachi 12:10) Now this fast was to be observed on the tenth day of Tisri, or their seventh month (which is made up of part of September and part of October); and then this day, which might well be called the fast, fell about the beginning of October; after which time, until March, they did not usually venture on the seas, especially their ships not being so able to bear a storm as ours are, and the art of navigation being not yet in any reasonable degree found out amongst them.
