Leviticus 23
14 Ref `And bread and roasted corn and full ears ye do not eat until this self-same day, until your bringing in the offering of your God -- a statute age-during to your generations, in all your dwellings.
15 Ref `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;
16 Ref unto the morrow of the seventh sabbath ye do number fifty days, and ye have brought near a new present to Jehovah;
17 Ref out 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.
