Bamidbar 18:27-29

Orthodox Jewish Bible

²⁷ And this your terumah shall be reckoned unto you, as though it were the grain of the threshing floor, and as the fulness of the winepress.

²⁸ Thus ye also shall offer a terumat Hashem of all your ma’aserot, which ye receive of the Bnei Yisroel; and ye shall give thereof terumat Hashem to Aharon HaKohen.

²⁹ Out of all your mattenot ye shall offer every terumat Hashem, of all the best thereof, even the set apart as kodesh part thereof out of it.
