Matthew 13:26

²⁶He said, “God’s Kingdom is as if a man should cast seed on the earth, ²⁷and should sleep and rise night and day, and the seed should spring up and grow, though he doesn’t know how. ²⁸For the earth bears fruit by itself: first the blade, then the ear, then the full grain in the ear. ²⁹But when the fruit is ripe, immediately he puts in the sickle, because the harvest has come.”
