תּלמוד אויף דברים 4:25

On the Ninth of Av itself what is the haftarah? Rav said: “How (איכה) has she become a harlot” (Isaiah 1:21). What is the section from the Torah? It has been taught: Others say, But if you will not obey me” (Leviticus 26:14-46); R. Nathan b. Joseph says: “How long will this people despise me” (Numbers 14:11-25); and some say, “How long shall I bear this evil congregation” (Numbers 14:26-46). Abaye said: Nowadays the custom has been adopted of reading [from the Torah] “When you shall bear children” (Deuteronomy 4:25-40), and for haftarah, “I will utterly consume them” (Jeremiah 8:13-9:23).
