Matthew 13:30

27 The servants of the householder came and said to him, `Sir, didn`t you sow good seed in your field? Where did this darnel come from?`

28 He said to them, `An enemy has done this.` The servants asked him, `Do you want us to go and gather them up?`

29 But he said, `No, lest perhaps while you gather up the darnel, you root up the wheat with them.

30 Let both grow together until the harvest, and in the harvest time I will tell the reapers, "First, gather up the darnel, and bind them in bundles to burn them; but gather the wheat into my barn."`"

31 He set another parable before them, saying, "The Kingdom of Heaven is like a grain of mustard seed, which a man took, and sowed in his field;

32 which indeed is smaller than all seeds. But when it is grown, it is greater than the herbs, and becomes a tree, so that the birds of the air come and lodge in its branches."

33 He spoke another parable to them. "The Kingdom of Heaven is like yeast, which a woman took, and hid in three measures of meal, until it was all leavened."
