(ii) Chittah (2406) - wheat, whether the grain or the plant:
Wheat. The most important cereal grass mentioned in the Bible. This was the bearded variety belonging to the genus Triticum. It was cultivated in Bible lands from early times <Gen. 30:14>. Egyptian wheat was the many-eared variety called "mummy wheat." This was the wheat of Pharaoh's dream <Gen. 41:5-57>. It was also depicted on Egyptian monuments.
Wheat was sown after barley in November or December. It was usually broadcast and then either plowed or trodden into the soil by oxen or other animals <Is. 32:20>. This grain was used for bread <Ex. 29:32>, and was also eaten parched <Lev. 23:14; Ruth 2:14>. It was used in ceremonial offerings <Lev. 2:1; 24:5-7> and as an article of commerce <Ezek. 27:17; Acts 27:38>.
When corn is mentioned in the Bible, it refers to wheat, as corn was not known in Bible times <Ps. 72:16; Matt. 12:1; Mark 4:28>. Jesus compared His death to a grain of wheat which must die to produce fruit <John 12:24>.
