Leviticus 23:14-16

American Standard Version

¹⁴ And ye shall eat neither bread, nor parched grain, nor fresh ears, until this selfsame day, until ye have brought the oblation of your God: it is a statute for ever throughout your generations in all your dwellings.

¹⁵ And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave-offering; seven sabbaths shall there be complete: ¹⁶ even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meal-offering unto Jehovah.
