The Shin on Head Tefillin: Three and Four Branches
Sources explain the halakhic requirement for the letter shin embossed on the head tefillin, including the traditional forms with three branches on the right and four branches on the left. The sources trace this practice from biblical command through Talmudic principle to later practical codification.
שִׁין שֶׁל תְּפִילִּין הֲלָכָה לְמֹשֶׁה מִסִּינַי
Songs of Praise in the Messianic Era
These sources explore the themes of future redemption, the ingathering of exiles, and the songs and praises that will characterize the days of Mashiach. They examine biblical and rabbinic perspectives on how Israel and the nations will celebrate and glorify God when redemption is fully realized.
בו נגאלו ובו עתידין ליגאל
Extinguishing Fire on Yom Tov: Gerama and Halacha
Sources examine the prohibition of extinguishing (kibuy) fire on Yom Tov and whether indirect causation (gerama) — such as turning off a gas source after grilling — may be permissible. The sources discuss the biblical and rabbinic dimensions of the prohibition, conditions for leniency in cases of significant loss, and how gerama is treated more leniently than direct extinguishing.
