Corn: The word so rendered (dagan) in Genesis 27:28,37, Numbers 18:27, Deuteronomy 28:51, Lamentations 2:12, is a general term representing all the commodities we usually describe by the words corn, grain, seeds, peas, beans. With this corresponds the use of the word in John 12:24.
In Genesis 41:35,49, Proverbs 11:26, Joel 2:24 ("wheat"), the word thus translated (bar; i.e., "winnowed") means corn purified from chaff. With this corresponds the use of the word in the New Testament (Matthew 3:12; Luke 3:17; Acts 7:12). In Psalm 65:13 it means "growing corn."
In Genesis 42:1,2,19, Joshua 9:14, Nehemiah 10:31 ("victuals"), the word (sheber; i.e., "broken," i.e., grist) denotes generally victuals, provisions, and corn as a principal article of food.
From the time of Solomon, corn began to be exported from Palestine (Ezekiel 27:17; Amos 8:5). "Plenty of corn" was a part of Issac's blessing conferred upon Jacob (Genesis 27:28; comp. Psalm 65:13).
