Ki Tavo, Ki Thavo, Ki Tabo, Ki Thabo, or Ki Savo (כִּי-תָבוֹא—Hebrew for "when you enter," the second and third words, and the first distinctive words, in the parashah) is the 50th weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading and the seventh in the Book of Deuteronomy. It comprises Deuteronomy 26:1–29:8. The parashah tells of the ceremony of the first fruits (בִּכּוּרִים, bikkurim), tithes, and the blessings from observance and curses (תוֹכֵחָה, tocheichah) from violation of the law.
