What do the individual ripened grain stems represent in the spiritual harvest?

Les explains that the Old Testament grain harvest comes to its fruition in the New Testament, so the scene is a picture not merely of wheat or barley but of a spiritual harvest. The scattered ripened stems are individuals—one here and one there—suddenly ripe while the rest of the crop is still a few days away. The Jew would pluck those ripened stems until he had a multitude and could make a sheaf, then present it to the priest as a wave offering. In the spiritual application, the ripening stems picture individuals gathered out of the whole, few compared to the whole but enough to make a sheaf. Jesus used the same analogy when He told the disciples to look at the fields white unto harvest, and He was speaking of mankind ready for a spiritual harvesting.
