הלכה אויף שמות 34:10

On the Ninth of Ab, the section read in the morning service is that beginning, "When thou shalt beget children" (Deuteronomy 4:25-40). The lesson from the Prophets is that beginning, "I will consume them" (Jeremiah 8:13-9:23). In the afternoon service, the sections beginning, "And Moses besought" (Exodus 32:11-14) and also (34:1-10) are read, as on the other fast-days and on those that are kept in commemoration of the calamities that befell our ancestors. These sections are read in the morning and afternoon services. The first person called up reads four verses from the section beginning, "And Moses besought." The second and third persons read from the section beginning, "Hew thee two tables of stone" till "That I am about to do with thee" (Exodus 34:1-10). On fast days appointed by the community because of existing calamities such as drought, pestilence or similar visitations, the Benedictions and Maledictions (Leviticus 26:3-46 or Deuteronomy 28:1-69) are read, so that the people, when they listen to them, may be moved to repent and their hearts be humbled.
