Amos said God would sift Israel like wheat, symbolizing the unchanging justice of Yahweh. [1] The apostles rubbed wheat on Sabbath, causing the spies to accuse Jesus of breaking the law. [2] The first weights were grains of wheat and other cereals, with fish or a goat as the first medium of exchange; later, the cow became a unit of barter. [3] God, like nature, permits good and evil to coexist until the end of life, just as wheat grows together with weeds. [4] The descendants of Adam traded improved wheat in the highlands of Mesopotamia, where they mingled with the descendants of Adamson. [5] The parable of the grain of wheat teaches that selflessly laying down one's life can lead to a more abundant existence on earth and in heaven. [6] The parable of wheat and weeds teaches that good and evil will coexist until the final judgment. [7]
