Traditionally, the book of Jonah is read, in its entirety, during the synagogue service on Yom Kippur afternoon. Nahum Sarna explains why (1990):

The major themes of the book are singularly appropriate to the occasion—sin and divine judgment, repentance and divine forgiveness.

What is remarkable is that the work is not at all about [the people] Israel. The sinners and penitents and the sympathetic characters are all pagans, while the anti-hero, the one who misunderstands the true nature of the one God, is none other than the Hebrew prophet. He is the one whom God must teach a lesson in compassion.

It is precisely these aspects of this sublime prophetic allegory, and in particular the subthemes of the book, that inform Yom Kippur. . . . [The book’s] universalistic outlook; its definition of sin as predominantly moral sin; its teaching of human responsibility and accountability; its apprehension that true repentance is determined by deeds and established by transformation of character (Jonah 3:10), not by the recitation of formulas, however fervent; its emphasis on the infinite preciousness of all living things in the sight of God (Jonah 4:10–11); and, finally, its understanding of God as “compassionate and gracious, slow to anger, abounding in loving-kindness” (Jonah 4:2)—all these noble ideas of the book of Jonah constitute the fundamentals of Judaism and the quintessence of Yom Kippur.

Israel will likely respond directly against Iran after yesterday’s attack, and has made known that it will calibrate its retaliation based not on the extent of the damage, but on the scale of the attack. The specifics are anyone’s guess, but Edward Luttwak has a suggestion, put forth in an article published just hours before the missile barrage: cut off Tehran’s ability to send money and arms to Shiite Arab militias.

In practice, most of this cash comes from a single source: oil. . . . In other words, the flow of dollars that sustains Israel’s enemies, and which has caused so much trouble to Western interests from the Syrian desert to the Red Sea, emanates almost entirely from the oil loaded onto tankers at the export terminal on Khark Island, a speck of land about 25 kilometers off Iran’s southern coast. Benjamin Netanyahu warned in his recent speech to the UN General Assembly that Israel’s “long arm” can reach them too. Indeed, Khark’s location in the Persian Gulf is relatively close. At 1,516 kilometers from Israel’s main airbase, it’s far closer than the Houthis’ main oil import terminal at Hodeida in Yemen—a place that was destroyed by Israeli jets in July, and attacked again [on Sunday].
