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.
In traditional Sabbath Torah reading, the parashah is divided into seven readings, or עליות, aliyot.
In the Old Testament or the Hebrew Bible, Jethro (/ˈdʒɛθroʊ/; Hebrew: יִתְרוֹ, Standard Yitro Tiberian Yiṯrô; "His Excellence/Posterity"; Arabic شعيب Shu-ayb) or Reuel was Moses' father-in-law, a Kenite shepherd and priest of Midian. In Exodus, Moses' father-in-law is initially referred to as "Reuel" (Exodus 2:18) but then as "Jethro" (Exodus 3:1). He was the father of Hobab in the Book of Numbers 10:29. He is also revered as the spiritual founder and chief prophet in his own right in the Druze religion, and considered an ancestor of all Druze.
Jethro is called a priest of Midian and became father-in-law of Moses after he gave his daughter, Zipporah, in marriage to Moses. He is introduced in Exodus 2:18.
Jethro is recorded as living in Midian, a territory stretching along the eastern edge of the Gulf of Aqaba in what is today northwestern Saudi Arabia. Some believe Midian is within the Sinai Peninsula. Biblical maps from antiquity show Midian on both locations.
Jethro's daughter, Zipporah (Rohaya), became Moses's wife after Moses had fled Egypt, having killed an Egyptian who was beating a Hebrew slave. Having fled to Midian, Moses intervened in a water-access dispute between Jethro's seven daughters and the local shepherds; Jethro consequently invited Moses into his home and offered him hospitality. However, Moses remained conscious that he was a stranger in exile, naming his first son (Jethro's grandson) "Gershom", meaning "stranger there".
