Vayikra 23:14-16

Orthodox Jewish Bible

¹⁴ And ye shall eat neither lechem, nor roasted grain, nor plump kernels until the same day that ye have brought a korban unto Eloheichem; it shall be a chukkat olam throughout your dorot in all your dwellings.

¹⁵ And ye shall count unto you from the day after the Shabbos, from the day that ye brought the omer of the wave offering; shevah shabbatot shall be complete,

¹⁶ Even unto the day after the seventh Shabbos shall ye count fifty days; and ye shall offer a minchah chadashah unto Hashem.
