Biblical Understanding based on the Record of Scripture
There are three harvests mentioned in the Law. Unleavened Bread, Harvest (Pentecost) and Ingathering (Tabernacles). Recently we have come to see the distinction between the barley harvest and the wheat harvest. Together they represent the first fruits. Paul is preparing the gentile converts of his day for the first or barley harvest. They are among the dead in Christ that will rise first.
