Week 42 is the last week of Tammuz, and is the first of the three weeks of mourning over the destruction of the Temple. The Torah section for this week describes the mannah, which would be received in different forms (like a seed, a dough, or a finished bread) depending on one's spiritual status. For those not completely righteous, the mannah was, in and of itself, a call for repentance.
Nebuzaradan said, "I will appease him." He then killed the members of the Great and Small Sanhedrins, then he killed youths and maidens, and then school-children. Altogether, he killed 940,000 people. Still the blood continued to boil, whereupon Nebuzaradan cried: "Zechariah, Zechariah! I have slain the best of them; do you want all of them destroyed?" At last the blood sank into the ground (Talmud, Gittin 57b).
