Leviticus 23:15-17

American Standard Version

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. ¹⁷ Ye shall bring out of your habitations two wave-loaves of two tenth parts of an ephah: they shall be of fine flour, they shall be baken with leaven, for first-fruits unto Jehovah.
