Tzav, Tsav, Zav, Sav, or in Biblical Hebrew Ṣaw (צַו — Hebrew for "command,” the sixth word, and the first distinctive word, in the parashah) is the 25th weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading and the second in the book of Leviticus. It constitutes Leviticus 6:1–8:36. The parashah is made up of 5,096 Hebrew letters, 1,353 Hebrew words, and 97 verses, and can occupy about 170 lines in a Torah scroll (סֵפֶר תּוֹרָה, Sefer Torah).
Jews read it the 24th or 25th Sabbath after Simchat Torah, generally in March or early April.
The parashah teaches how the priests performed the sacrifices and describes the ordination of Aaron and his sons.
