(lit. "uncircumcised"---the fruit of a tree during its first three years). Tenth tractate of Order
Zera'Im in the Mishnah. Its three chapters discuss the laws forbidding the derivation of any benefit from fruit trees in Erets Israel during the first three years of growth (cf. Lev. 19:23-25). The Mishnah describes which trees are exempt from the laws of
orlah, the law applying to mixtures of
orlah with other tithes or permitted fruits, and using
orlah-fruit dye or cooking food over a fire fueled by
orlah-fruit peelings. The law against using
orlah is a rabbinic injunction also outside Israel. The subject-matter is amplified in the Jerusalem Talmud and the
Tosefta.
