Yitro, Yithro, Yisroi, Yisrau, or Yisro (יִתְרוֹ — Hebrew for the name 'Jethro,' the second word and first distinctive word in the parashah) is the seventeenth weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading and the fifth in the book of Exodus. It constitutes Exodus 18:1–20:23. The parashah is the shortest of the weekly Torah portions in the book of Exodus (although not the shortest in the Torah), and is made up of 4,022 Hebrew letters, 1,105 Hebrew words, and 75 verses. The parashah tells of Jethro's organizational counsel to Moses and God's revelation of the Ten Commandments to the Israelites at Mount Sinai. Jews read it the seventeenth Sabbath after Simchat Torah, generally in January or February. Jews also read part of the parashah, Exodus 19:1–20:23, as a Torah reading on the first day of the Jewish holiday of Shavuot, which commemorates the giving of the Ten Commandments.
