“You find three verses [two in this week’s portion] that command you to rejoice in the Feast of Tabernacles….For Passover, however, you will not find even one command to rejoice. Why not?” Several explanations are offered in the commentary for the variations of joy-related commandments (there is one command to rejoice for Shavuot). Each explanation suggests important ideas about the calendar, including the upcoming fall holidays, and reciting Hallel throughout the year.

The mighty kings Og and Sihon — mentioned in Devarim/Deuteronomy 1:4, with more detail in chapter 3 — were defeated while the Israelites were still in the wilderness (Numbers/Bamidbar 20, 21). But Og and Sihon provide a direct connection to several prayers as well as to contemporary debate about what, more generally, is a “morally uplifting offering” in prayer.
The kings are also linked to midrashim on Genesis and Exodus, and, less directly, to MAZON: A Jewish Response to Hunger and an array of texts through the years. In fact, a brief exploration of Og and Sihon suggests that, as hypothesized about world population, any given Jewish text is no more than six degrees of separation from any other.
