Matthew 13:31-33

Another parable set he before them, saying, The kingdom of heaven is like unto a grain of mustard seed, which a man took, and sowed in his field: which indeed is less than all seeds; but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the heaven come and lodge in the branches thereof. Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till it was all leavened.
