Matthew 13:31-33

³¹ He put another parable before them, saying, “The kingdom of heaven is like a grain of mustard seed that a man took and sowed in his field. ³² It is the smallest of all seeds, but when it has grown it is larger than all the garden plants and becomes a tree, so that the birds of the air come and make nests in its branches.” ³³ He told them another parable. “The kingdom of heaven is like leaven that a woman took and hid in three measures of flour, till it was all leavened.”
