Israel's success in military cyber-operations and cyber-security, from disrupting Iranian nuclear development to covert intelligence gathering, is well known. It has given birth to a cluster of companies that have made Tel Aviv a global hub for cyber-security.

Alon Arvatz is CEO and co-founder of PointFive, a new cybersecurity start up based in Tel Aviv, and the author of a new book, The Battle for Your Computer: Israel and the Growth of the Global Cyber-Security Industry. With Mosaic editor Jonathan Silver, he talks here about some of the factors that make Israeli companies so competitive in cybersecurity, how military and intelligence applications of cyber technology have changed over time, how he thinks they will change in the future, how these technological capabilities relate to policy and politics, what kind of regulatory oversight is appropriate for the industry, and much else.

“When a man or woman shall commit any sin that men commit, to do a trespass against the Lord, and that person be guilty; then they shall confess their sin which they have done: and he shall make restitution for this trespass in full.” So reads chapter 5 from the book of Numbers. Repentance is on the Jewish mind these days. The time between Rosh Hashanah and Yom Kippur is called the Ten Days of Teshuva—the Ten Days of Repentance—and during it observant Jews engage in prayer and penitence.

What is repentance? How does it operate? What’s actually happening in the mind of the penitent?

Daniel Rynhold is dean of the Bernard Revel Graduate School of Jewish Studies and professor of Jewish philosophy at Yeshiva University. He has thought and written much about repentance and sees it as a way to illustrate some of the most interesting contrasts between medieval and modern philosophers. Joining Mosaic editor Jonathan Silver here to discuss the subject, he focuses on three major thinkers, two from within the Jewish tradition and one outside of it.

The first is Rabbeinu Yonah, the 13th-century author of the rabbinic work The Gates of Repentance. The second is Joseph B. Soloveitchik, known as the Rav, who was perhaps the central intellectual figure of post-war Modern Orthodoxy. The third is the German philosopher Friedrich Nietzsche, a famous critic of the Enlightenment, of liberalism, and of modernity. The last two are the focus of his book, written with Michael Harris, Nietzsche, Soloveitchik, and Contemporary Jewish Philosophy, published in 2018 by Cambridge University Press.

Tonight begins Rosh Hashanah, when Jewish communities celebrate the new year and, as part of this celebration, read chapter 22 of Genesis. This contains the famous story in which God asks Abraham to take his son Isaac to a mountain and offer him there as a sacrifice.

What is this passage all about? What does it mean? What can be learned about Abraham, about Isaac, or about God by reading it carefully? Joining Mosaic’s editor Jonathan Silver today to discuss these questions is Jon D. Levenson, a professor of Jewish studies at Harvard Divinity School and frequent Mosaic contributor. Levenson has written about this episode in several books, including The Death and Resurrection of the Beloved Son published in 1993 by Yale University Press, and also in Inheriting Abraham, published in 2012 by Princeton University Press.

Akeidat Yitzḥak, the binding of Isaac, as the Jewish people traditionally refer to this episode, has a long afterlife in Christian and Muslim traditions; it is also a centerpiece of philosophical reflection among modern thinkers like Immanuel Kant and Soren Kierkegaard. Reading the text now in the aftermath of those later reflections, it’s difficult to retrieve its original meaning. The temptation is overwhelming to propose moral justifications for Abraham and for God, to excuse or at least to try to soften the drama of Genesis 22.  To hear what the text of the Hebrew Bible really might have to say in response to that temptation requires undoing some modern assumptions—a task that Levenson and Silver take up.

Last Saturday, supporters and opponents of Eritrea’s president, Isaias Afwerki, confronted one another in violent clashes. Yet rather than in Asmara, Eritrea’s capital city, this confrontation took place in the streets of south Tel Aviv. In the second half of the 2000s, east African migration to Israel began to accelerate. Since then, in part due to changes in labor policies and law enforcement and in part to a barrier wall erected along the Egypt-Israel border, the number of new east African migrants has fallen precipitously. Nevertheless, although statistics are hard to come by with great precision, there are probably around 40,000 non-Jewish African migrants living in Israel today.

What brings these mainly Ethiopian, Eritrean, and Sudanese immigrants to the cities and towns of Israel? And how does and how should Israel distinguish between those seeking humanitarian asylum and those looking for work opportunities and social benefits?

These questions have become major points of debate in Israel. Some argue that the state must act in the world as a corrective to the Jewish experience of statelessness in history—that since Jews have so often been migrants and refugees and dependent on the help of others, Israel must help others in need when it can. Others argue that Israel—the political answer to the problems of Jewish statelessness—has an overriding moral obligation to welcome and to secure the lives and liberties of Jews—that it has a special obligation to pursue the ingathering of the Jewish diaspora and so to make a distinction between Jewish and non-Jewish immigrants.

To discuss these issues, Yonatan Jakubowicz, formerly an advisor to Israel’s Minister of Interior, and a founder of the Israeli Immigration Policy Center, joins Mosaic editor Jonathan Silver.
