The Mishnah contains four chapters. The first two discuss fasts decreed because of drought, including the determination of the time when the rain should descend; the prayers for those fasts; those exempt from the fasts; and the days when fasts may not be decreed. Chapter 1, from the middle of halakhah 2 onward, derives completely from the Mishnah of Meir. Chapter 2:6–7 is a source dealing with the men of the mishmarot and ma'amadot, an account given in its entirety although only the first part is relevant to the subject of fasting. The third chapter discusses fasts decreed for reasons other than drought. Chapter 4:1–5 deals with the recital of the priestly blessings on fast days. Although only the first halakhah is devoted to this subject, the whole of the source used by Judah ha-Nasi containing this halakhah is given. This too is derived from the Mishnah of Meir and also contains details of the description and the halakhot of the ma'amadot (4:2–4) during which the priestly blessings were uttered as they were on fast days. In connection with the ma'amadot, the times of the wood offerings of the priests and the people are described (4:5). Chapter 4:6–7 deals with the permanent fast days of the 17th of Tammuz and the Ninth of Av, their causes, and the detailed laws of the Ninth of Av and the preceeding days. Chapter 4:8, dealing with the ancient ceremonies of betrothal on the 15th of Av and the Day of Atonement, is a supplement to 4:5 where the 15th of Av is mentioned. The tractate closes with a later aggadic addition about the Temple so as to end on a note of comfort.
