Easton's 1897 Bible Dictionary:

Cummin
   (Heb. kammon; i.e., a "condiment"), the fruit or seed of an
   umbelliferous plant, the Cuminum sativum, still extensively
   cultivated in the East. Its fruit is mentioned in Isa. 28:25,
   27. In the New Testament it is mentioned in Matt. 23:23, where
   our Lord pronounces a "woe" on the scribes and Pharisees, who
   were zealous in paying tithes of "mint and anise and cummin,"
   while they omitted the weightier matters of the law." "It is
   used as a spice, both bruised, to mix with bread, and also
   boiled, in the various messes and stews which compose an
   Oriental banquet." Tristram, Natural History.
