Leviticus 23:15-17

¹⁵'And ye have numbered to you from the morrow of the sabbath, from the day of your bringing in the sheaf of the wave-offering: they are seven perfect sabbaths;

¹⁶unto the morrow of the seventh sabbath ye do number fifty days, and ye have brought near a new present to Jehovah;

¹⁷out of your dwellings ye bring in bread of a wave-offering, two loaves, of two tenth deals of flour they are, with yeast they are baken, first -fruits to Jehovah.
