Mark 4:26-29

“The kingdom of God is like this,” he said. “A man scatters seed on the ground. He sleeps and rises night and day; the seed sprouts and grows, although he doesn’t know how. The soil produces a crop by itself — first the blade, then the head, and then the full grain on the head. As soon as the crop is ready, he sends for the sickle, because the harvest has come.”
