Tzav, Tsav, Zav, or Sav (צו — Hebrew for "command,” the sixth word, and the first distinctive word, in the parshah) is the 25th weekly Torah portion (parshah) in the annual Jewish cycle of Torah reading and the second in the book of Leviticus. It constitutes Leviticus 6.1–8:36. Jews in the Diaspora read it the 24th or 25th Sabbath after Simchat Torah, generally in March or early April. The parshah teaches how the priests performed the sacrifices and describes the ordination of Aaron and his sons.
