The last instruction that Moses receives on Mount Sinai, before God gives him the inscribed tablets, before the incident of the Golden Calf, is the reminder about the importance of the sabbath.
This week's Torah portion contains one of the most dramatic events in the entire Torah, the incident of the Golden Calf. Moses has been on Mount Sinai for a very long time, too long for those Israelites who still carry Egypt in their hearts to wait.
On July 2, 2014, the prestigious science journal Nature retracted two heralded papers in the field of stem cell research, papers it had published only a few months earlier. The articles described a revolutionary process called STAP, where biologists subjected mature adult cells to physical stresses and transformed them into stem cells. Yet, in the editorial announcing the papers' retraction, Nature's editors reported that the "data that were an essential part of the authors' claims had been misrepresented" and that the authors' work was marred by "sloppiness" and "selection bias" ("Editorial: STAP retracted," Nature, vol. 511, no. 7507, July 2, 2014). All told, as the journalist Dana Goodyear has written, "a far-reaching and sensational conjecture" was "defeated by flaws that were at best irreparable and at worst unconscionable" ("The Stress Test," The New Yorker, February 29, 2016, pp. 46-57).
In this week’s Torah portion, Sh’lach L’cha, 12 scouts are sent into the Promised Land to bring back a report to the former slaves in the wilderness. Ten of them report that the Land flows with milk and honey, but it will be difficult to conquer. Two spies present a different point of view, projecting an energizing sense of hope over a paralyzing sense of fear.
