The word so rendered (dagan) in Genesis 27:28, 37; Num. 18:27; Deut. 28:51; Lam. 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; Prov. 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 (Matt. 3:12; Luke 3:17; Acts 7:12). In Ps. 65:13 it means “growing corn.”
