Matthew 13:29

26 But when the green stem came up and gave fruit, the evil plants were seen at the same time.

27 And the servants of the master of the house came and said to him, Sir, did you not put good seed in your field? how then has it evil plants?

28 And he said, Someone has done this in hate. And the servants say to him, Is it your pleasure that we go and take them up?

29 But he says, No, for fear that by chance while you take up the evil plants, you may be rooting up the grain with them.

30 Let them come up together till the getting in of the grain; and then I will say to the workers, Take up first the evil plants, and put them together for burning: but put the grain into my store-house.

31 He put another story before them, saying, The kingdom of heaven is like a grain of mustard seed which a man took and put in his field:

32 Which is smaller than all seeds; but when it has come up it is greater than the plants, and becomes a tree, so that the birds of heaven come and make their resting-places in its branches.
