Mark 4:26-29 (New King James Version – NKJV)

The Parable of the Growing Seed

And He said, “The kingdom of God is as if a man should scatter seed on the ground, and should sleep by night and rise by day, and the seed should sprout and grow, he himself does not know how.

For the earth yields crops by itself: first the blade, then the head, after that the full grain in the head.

But when the grain ripens, immediately he puts in the sickle, because the harvest has come.”
