Treatise in the Mishnah, Tosefta, and both Talmuds, devoted chiefly to the fast-days, the practises peculiar to them, and the prayers which must be said thereon. In most editions this treatise is the ninth in the mishnaic order of Seder Mo'ed, and is divided into four chapters containing thirty-four paragraphs in all. The contents may be summarized as follows:
The Tosefta to this treatise contains much that elucidates and supplements the Mishnah. Especially noteworthy are the account of the origin of the priestly classes (iv:2), the changes which affected them after the return from the Captivity, and how they were again subdivided (ii:1).
