Smith’s Bible Dictionary
Rye: (Heb. cussemeth) occurs in (Exodus 9:32; Isaiah 28:25) in the latter the margin reads "spelt." In (Ezekiel 4:9) the text has "fitches" and the margin "rie." It is probable that by cussemeth "spelt" is intended. Spelt (Triticum spelta) is grown in some parts of the south of Germany; it differs but slightly from our common wheat (T. vulgare).
