Tractate Temurah is a tractate of the Babylonian Talmud, the greater part of which is an elaboration of the Law laid down in Leviticus 27:10 regarding dedication of an animal for sacrifice.
In Jewish Law, temurah (Hebrew: תמורה, literally: "exchange") is the prohibition against attempting to switch the sanctity of an animal that has been sanctified for the Temple in Jerusalem with another non-sanctified animal. It explicitly stated in Leviticus 27:33. According the law, both animals become sanctified, and the person who attempted the transfer is punished with lashes.
