Mark 4:26-29

²⁶He said, "So is the kingdom of God, 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, he doesn`t know how. ²⁸For the earth bears fruit: first the blade, then the ear, then the full grain in the ear. ²⁹But when the fruit is ripe, immediately he puts forth the sickle, because the harvest has come."
