Bamidbar 18:28-30

Orthodox Jewish Bible

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.

³⁰ Therefore, thou shalt say unto them, When ye have raised up the best thereof from it, then it shall be counted unto the Levi’im as the increase of the threshing floor, and as the increase of the winepress.
