Mark 4:26-29

MLV(i) 26 And he said, So is the kingdom of God, as if a man cast seed upon the earth; 27 and he should sleep and should arise night and day, and the seed may sprout and should lengthen, he does not know how. 28 For the earth is bearing-fruit by herself; first the blade, thereafter the top, then the full grain in the top. 29 But whenever the fruit is giving way, immediately he sends forth the sickle, because the harvest is standing ready.
