Mark 4:27-30

²⁷and should sleep, and rise night and day, and the seed should spring and grow up, he knoweth not how.

²⁸For the earth bringeth forth fruit of herself; first the blade, then the ear, after that the full corn in the ear.

²⁹But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come.

³⁰And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it?
