Ki Tisa, Ki Tissa, Ki Thissa, or Ki Sisa (כִּי תִשָּׂא — Hebrew for “when you take,” the sixth and seventh words, and first distinctive words in the parashah) is the 21st weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading and the ninth in the book of Exodus. It constitutes Exodus 30:11–34:35. The parashah is the longest of the weekly Torah portions in the book of Exodus (although not the longest in the Torah), and is made up of 7,424 Hebrew letters, 2,002 Hebrew words, and 139 verses, and can occupy about 245 lines in a Torah scroll (סֵפֶר תּוֹרָה, Sefer Torah). (The longest parashah in the Torah is Naso.)
Jews read it on the 21st Sabbath after Simchat Torah, generally in late February or March. Jews also read the first part of the parashah, Exodus 30:11–16, regarding the half-shekel head tax, as the maftir Torah reading on the special Sabbath Shabbat Shekalim (February 9, 2013 (read with parashah Mishpatim); and March 1, 2014 (read with parashah Pekudei)). Jews also read parts of the parashah addressing the intercession of Moses and God’s mercy, Exodus 32:11–14 and 34:1–10, as the Torah readings on the fast days of the Tenth of Tevet, the Fast of Esther, the Seventeenth of Tammuz, and the Fast of Gedaliah, and for the afternoon (Mincha) prayer service on Tisha B'Av. Jews read another part of the parashah, Exodus 34:1–26, which addresses the Three Pilgrim Festivals (Shalosh Regalim), as the initial Torah reading on the third intermediate day (Chol HaMoed) of Passover. And Jews read a larger selection from the same part of the parashah, Exodus 33:12–34:26, as the initial Torah reading on a Sabbath that falls on one of the intermediate days of Passover or Sukkot.
The parashah tells of building the Tabernacle, the incident of the Golden Calf, the request of Moses for God to reveal God’s attributes, and how Moses became radiant.
