Matthew 13:31-35

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.

33 Another story he gave to them: The kingdom of heaven is like leaven, which a woman took, and put in three measures of meal, till it was all leavened.

34 All these things Jesus said to the people in the form of stories; and without a story he said nothing to them:

35 That it might come true which was said by the prophet, Opening my mouth, I will give out stories; I will give knowledge of things kept secret from before all time.
