Tetzaveh, Tetsaveh, T'tzaveh, or T'tzavveh (Hebrew: תְּצַוֶּה, romanized: Təṣavve, lit. '[you] shall command', the second word and first distinctive word in the parashah) is the 20th weekly Torah portion (פָּרָשָׁה‎, parashah) in the annual Jewish cycle of Torah reading and the eighth in the Book of Exodus. The parashah reports God's commands to bring olive oil for the lamp (מְנוֹרָה‎, Menorah), make sacred garments for the priests (כֹּהֲנִים‎‎, kohanim), conduct an ordination ceremony, and make an incense altar.

It constitutes Exodus 27:20–30:10. The parashah is made up of 5430 Hebrew letters, 1412 Hebrew words, 101 verses, and 179 lines in a Torah scroll. Jews read it the 20th Shabbat after Simchat Torah, in February or March.

In traditional Sabbath Torah reading, the parashah is divided into seven readings, or עליות‎, aliyot.

In the first reading, God instructed the Israelites to bring Moses clear olive oil, so that Aaron and his descendants as High Priest could kindle lamps regularly in the Tabernacle. God instructed Moses to make sacral vestments for Aaron: a breastpiece (חֹשֶׁן‎, Ḥoshen), the Ephod (אֵפוֹד‎), a robe, a gold frontlet inscribed "holy to the Lord," a fringed tunic, a headdress, a sash, and linen breeches.

In the second reading, God detailed the instructions for the breastpiece. God instructed Moses to place Urim and Thummim inside the breastpiece of decision.

In the third reading, God detailed the instructions for the robe, frontlet, fringed tunic, headdress, sash, and breeches. God instructed Moses to place pomegranates and gold bells around the robe's hem, to make a sound when the High Priest entered and exited the sanctuary, so that he would not die.

In the fourth reading, God laid out an ordination ceremony for priests involving the sacrifice of a young bull, two rams, unleavened bread, unleavened cakes with oil mixed in, and unleavened wafers spread with oil. God instructed Moses to lead the bull to the front of the Tabernacle, let Aaron and his sons lay their hands upon the bull's head, slaughter the bull at the entrance of the Tent, and put some of the bull's blood on the horns of the altar. God instructed Moses to let Aaron and his sons lay their hands upon the first ram and slaughter it, sprinkle its blood, and dissect it.

In the fifth reading, God instructed Moses to take one of the rams, let Aaron and his sons lay their hands upon the ram's head, slaughter the ram, and put some of its blood and on the ridge of Aaron's right ear and on the ridges of his sons' right ears, and on the thumbs of their right hands, and on the big toes of their right feet.
